Methods using social topical adaptive networking system

ABSTRACT

A machine-implemented social networking system builds up and repeatedly refreshes a hierarchy tree containing topic nodes. New nodes are added as new topics emerge in online public forums. Each topic node can link to an on-topic real time chat room whose occupants are currently discussing the topic of the node. A chat room can be pointed to by more than one node if the room is discussing multiple topics. Rooms can migrate from node to node as room topic dynamically changes. A system user who explicitly or inferentially wishes to be invited into a chat room which is on-topic with what the user is currently focused upon can do so by use of a node-seeking automated process. The process operates in the background and seeks out nodes of the hierarchy tree that currently have topics appearing to be the same as or similar to what topics the user appears to have in mind. Content browsing experience of the user is enhanced by addition of an invitations displaying subsystem that automatically invites him or her to co-compatible chat rooms currently discussing the topic(s) the user appears to have in mind. One of the many topics that a user may inferentially have in mind is that of being at a given location as reported by the user&#39;s GPS and wondering what best to do at that location and time.

FIELD OF DISCLOSURE

The present disclosure of invention relates generally to real timesocial networks and to production of on-topic search results includingthat of automatically producing matches between currently online peoplefor instant engagement in real time with one another in forums such aschat rooms. One aspect of the disclosure relates more specifically tohelping isolated online users of a network (or even strangers at asocial gathering, e.g., a large business conference) in automaticallyfinding one another at times when they are in the mood to do so and whenthey have roughly concurrent focus on same or similar content and/orwhen they have approximately concurrent interest in a same or similarparticular topic or topics and/or when they have current personalityco-compatibility for instantly chatting with, or for otherwiseexchanging information with one another in short order online (or evenin person) and for example with regard to the content and/or topic ofshared current focus or with regard simply to a likelihood that theyhave current personality co-compatibility for instantly chatting online(or even in person) with each other and potentially developing focus ona particular topic of common interest. Another aspect of the disclosurerelates to providing a real time changing indexing tree havinghierarchically interconnected nodes representing topics, where theconfiguration of the tree changes dynamically in response to real timereactions of users to online content. In one embodiment, nodes of thetree correspond to topics in a dynamically changing topic space and thenodes link to on-topic chat rooms and/or to on-topic search results.Domain and topic nodes in the tree may include unconventional ones suchas, My Current Location Is: . . . (fill in the blank with locationdetermined by GPS or other means) and topics under that domain mayinclude, Fun Things to do for My Demographic Group at this location andthis time or soon after.

DESCRIPTION OF RELATED TECHNOLOGY AND USAGE

The internet is one example of a network supported, public communicationand data exchange system that enables isolated users to individuallybrowse through an almost unlimited volume of informational content.Users can peruse through daily, hourly, or even minute-by-minute updatednews publications, industry journals, blogs, tweets, list serves, videogalleries (e.g., You Tube™), photo galleries (e.g., Flicker™), and soforth. For almost any general or unique topic a given first user may becurrently interested in, or focused on, corresponding content is usuallyavailable somewhere out on the internet (or via another publicinformation distributing means) for looking at by the first user (if theuser knows its URL or other content access pathway to that informationalcontent). The same content is typically available for concurrent studyby other users. The specific topic areas that are of interest to eachuser may span from those that are socially popular (i.e., the latestfads), socially acceptable and/or economically valuable to ones thatmight be taboo or even border on the illegal. It is not the intent ofthis disclosure to pass judgment on what topics of focus people mayapprove of or not approve of, but rather to point out that people'sinterests and immediate areas of focus (current attention) can be wide,varied over time and can often coincide by happenstance with the sameinterests of many others or with a same esoteric interest of a highlyesoteric handful of other people, where the people who share a topic ofinterest may be situated (clustered) in a same local community orsparsely spread around the world.

Much of online content (and/or content that is locally stored on auser's local data storage device) is accessed by human users in arelatively non-social framework. That is to say, and by way of example,that a first isolated user in suburban Utah may have been scanningthrough large volumes of online content while for most of the timeexhibiting little interest in the browsed through content. However,surprisingly, in the last few minutes (or longer, or shorter), she beganto keenly study and with great interest a particular article in anonline posting of “Celebrity Sensations Magazine” (here, a fictitiousname for a possible online magazine and not to be confused with amagazine of same or similar name if any exists). Unbeknownst to thefirst user, another isolated user in rural Nevada (whom the first userhas not met) is doing the same thing at about the same time, namely,having settled into looking at the same web page, the same article andalso becoming substantially engaged emotionally or otherwise involvedwith the same material (the same content). The content intake andinformation appreciation experience for each of the first and secondisolated users might be much richer and more satisfactory if only theseisolated users could connect online essentially instantly with oneanother and exchange ideas or insights or even develop new ideas aboutthe specific article that they are now reading and are now substantiallyengaged with. However, heretofore there was no automated and easy-to-usemechanism available for bringing such isolated online users together atthe moment of their concurrent focus on same or similar content and atthe moment of their concurrent substantial involvement (e.g., emotionalor other involvement) with that content, where for example, themechanism invites both of them to join a mutually acceptable, real timeonline chat or another such online informational exchange forum thatfocuses on the content and/or topic of their concurrent mutual focus.

As known to those skilled in the art of internet chat rooms, so-calledinstant chats can be invoked in numerous ways, including but not limitedto: IRCs (Internet Relay Chats), HTML rooms and Java rooms. When suchchat rooms are employed, it appears to a first user that one or moreother persons are substantially instantly reading (or otherwiseperceiving, e.g., within one or a few seconds) what the first user postsinto the chat room frame and that the other person(s) are responding insubstantially real time to those actions by, for example, almostinstantly writing back (instant back and forth messaging).

As is further known to those skilled in the art of internet chat rooms,such person-to-person interconnections can be private ones or ones opento the public. People who do not know each other (in the real world, ina virtual reality world, or otherwise) generally cannot meet one anotherfor a first time in a private chat room because one must know the otherahead of time (and/or have some pre-existing “friendship” or “chatbuddy” relationship with the other) in order to post an invitation andthus induce entry into the private chat room. Thus, in the example givenabove, the two isolated and concurrent readers of same content in theonline Celebrity Sensations Magazine (a fictitious name) will heretoforenot have had a convenient means by way of which to join in a privateroom because they do not know of each other's existence or identity.Moreover, they do not know about the concurrency and commonality oftheir attention on same content or their interest in apparently the sametopic (content and topic are not always the same thing as will be seenbelow). Thus they have essentially nothing to entice them to then meetin a same online chat room (private or public). On the other hand,public chat rooms often allow just about anyone who is aware of the roomto join in its transactions (e.g., electronic conversations). Because ofthis complete openness, public chat rooms are often quickly overtaken byso-called “trolls” (a pejorative term for offensive or impolitepersonalities) and these discussion-hogging people tend to reduce thediscourse to a relatively low level of common denominator (e.g., adhominem attacks, profanity, digression from original topic ofdiscussion, etc.). Thus, useful interchange is very difficult to obtainin wide open public chat rooms and many users who would otherwise enjoypolite and civil discourse with similar minded peers in an online chatroom avoid public ones at least for this reason.

The latter situation is unfortunate because much could be gained fromexchanges between people (e.g., peers) who may meet each otherelectronically for a first time and have a concurrent common focus onsame or similar content and/or interest in a same or similar topic thatthey wish to discuss and/or collaborate with others who are also engagedwith the corresponding subject matter at that moment. Also, it would behelpful if meeting strangers can somehow increase the odds that they areco-compatible with one another in terms of chat personalities and/or inproficiency regarding the topic or content of common interest.

Online is not the only place where strangers can meet. Large businessconferences is another example. Two people can be at a same largebusiness conference and in short walkable proximity of each other butsurrounded by hundreds of other people. The two attendees to theconference may not know each other, and yet they may have much to gainif they were to meet in person and exchange information in real timeabout specific topics of concurrent common interest. But since theydon't know each other and are not aware of their mutual concurrentinterest in certain specific topics and of their physical proximity toone another, as well as of their co-compatibility for chatting with oneanother, it is likely that without more, they will not meet. It will bea missed opportunity for mutual gain. Heretofore, an easy to useautomated system was not available for joining together people who havesame topics of concurrent interest on their minds and who areco-compatible for chatting with one another either online or even inperson.

SUMMARY

Structures and methods are provided in accordance with the presentdisclosure of invention for creating a social network driven indexingsystem that can, as one option, instantly cluster people with concurrentfocus on a same topic into currently on-topic chat rooms and that canadditionally or as an independent option, generate on-topic searchresults tailored to user preferences regarding the topic of currentinterest. In one embodiment, the system almost instantly provides firstlinks (e.g., invitations) to online chat rooms (or to othersubstantially real time informational exchange forums provided via awired or wireless communications network) for people who happen to befocused on same or similar content at substantially the same time,and/or who happen to be interested in a same or similar topic and/or whoare chat-wise co-compatible with one another. The offered first links orinvitations allow such people (including those who probably would nothave otherwise linked to each other) to meet within the offered chatrooms (or even in person in some instances) and to share information ordiscussion regarding, for example, same or similar content of currentmutual focus and/or same or similar topics of current mutual interest.In the same or another embodiment, the system almost instantly providessecond links (e.g., further research and/or activity suggestions) toonline data resources whose content currently substantially relates to atopic that appears to currently be on the user's mind. The offeredsecond links or further research/activity suggestions allow people tolocate on-topic additional material (e.g., the most current on-topicmaterial) even without joining a chat room. In one embodiment, theprovision of invitations and/or recommendations occurs by machineautonomous action—in other words, the user is not consciouslyparticipating in generation of the invitations and/or recommendations,except perhaps to consciously approve activation or continuance of abenign form of spyware that will spy on the user's current activitiesand infer from those activities what content, if any, is currently ofinterest to the user, what topic, if any, is currently on the user'smind and/or what kinds of other people are currently co-compatible forchatting with the user online or otherwise (e.g., even in person).

It is to be understood, Incidentally, that when this disclosure mentionsan online web page (online content) that a given user is focusing his orher attention on, the disclosure is not intended to be limiting itsscope to HTML or otherwise coded web pages or to content providedexclusively by a user's one computer or exclusively through theinternet. Any form of network-provided or broadcast-provided ormulti-cast-provided presentation of informational content to users(whether digital or analog) is contemplated. All that is needed is thatthe user can focus his or her attention on the presented content, thatthe user's focus can be automatically detected by machine means and thatthe content can be automatically identified by machine means as contentthat is substantially similarly also available to other users in roughlythe same time span. In other words, the present disclosure contemplatessituations where two or more separated users are watching a same livebroadcast of a television show (analog or digital), or are almostconcurrently watching a same YouTube™ or other online video stream, orare concurrently viewing a pre-recorded show from their personalrecording devices (e.g., TiVO™) or are listening to a same radio show,and so forth, and where the identity of the content can be automaticallydetermined by machine means and preferably where the degree of userinvolvement with the content can also be automatically determined bymachine means.

The point being made here is that two or more users can be focusing atroughly the same time on same or similar machine-generated content(e.g., digital content) and an automated means is present foridentifying the content they are focusing their attention on at themoment and reporting the occurrence of the same automatically to areports-collecting and match-making centralized system. The disclosurewill be easier to understand however, by first starting with the casewhere the content presenting apparatus is a user's local data processingmachine system (e.g., a user-operated and user-servicing digitalcomputer such as one having a CPU, memory & network interface) and thecontent being provided can be identified by means of a URL code(Universal Resource Locater code) or other such page identifying codeand where the content identifying code (e.g., URL) is already inpossession of or directly accessible by software executing on the user'slocal data processing machine. Also, because the inclusion of headingmarkers, meta-tags and the like in HTML (HyperText Markup Language) orXML (Extensible Markup Language) coded web pages is understood by thoseskilled in the art, it will be easier to start with such a commonlyunderstood form of content presentation and explain how topical hintsare often invisibly embedded in such content in the form of meta-tags,heading start/stop braces, and the like. In a more complex situationwhere plural users are watching or listening to a live analog broadcast,for example, of a soccer game, hints about the topic(s) associated withwhat is being watched (and/or listened to) may have to come from anancillary real time digital source (e.g., automated captioning text forthe deaf for that same content providing channel) whose output can betime-wise synchronized with the analog broadcast content that the usersare focusing upon and whose digital output can thus be used to infer aprobable topic of common interest then probably present on the pluralusers' minds. It will be seen that the users can be linked to oneanother through an on-topic node and that, because the on-topic nodeserves as sort of a portal for identifying and/or joining togethergroups of people who probably have a same topic in mind, the on-topicnode can also serves as sort of a common collection point for collectingmost-current data about the topic where the collected data (e.g., recentor common URL hints) can be collected and ranked based on the type ofpeople who implicitly pass through the portal-like node (e.g., where onetype of such people are licensed and/or otherwise credentialed expertsin the topic being handled by the on-topic node).

Moreover, it is to be understood that the initial embodiments discussedherein will assume single users each privately positioned in front ofhis or her personal computer. However, it will be seen later that facerecognition software may be used in group situations where differentpeople are taking turns in interfacing with a same computer and thecomputer may then automatically switch user profiles upon automaticallyrecognizing that a different user is now sitting in front of thecomputer webcam and computer screen and interfacing with that localclient machine.

In one embodiment, structures and methods for collectingcontent-identifying reports and/or reports about a given user's level offocused interest in that content, operate under the auspices of adistributed and automated match-making and invitations-generating system(MM-IGS). The MM-IGS collects (e.g., uploads) information (Current Focusinformation, also referred to herein as CFi data) about the content thatparticipating individual users are currently focusing on, about theiremotional reactions to the focused upon content, and also additionalpersonhood information about their backgrounds and preferences. Usingthis information, the MM-IGS automatically generates clustering mapswhich cluster together in an appropriate co-compatibility space, variousones of plural users who appear to be co-focused on same or similarcontent, and/or who appear to have same or similar topics on their mindsand/or who appear to have co-compatible personalities and/or who appearto have same or similar emotional reactions regarding the topic orcontent being focused upon. The MM-IGS automatically generatesinvitations and sends the invitations to closely clustered together onesof its users to thereby invite them to join each other in an online chatroom (or other network supported information exchange forum, e.g., arestricted access blog, a peer-to-peer forum) whose occupants are or areexpected to be focused upon the same or similar content, on the same orsimilar topic and/or to exhibit same or similar general emotionalreactions to the topic and/or to the focused upon content. Users whoaccept the invitations are automatically linked to the real timeinformational exchange forums (e.g., chat rooms) that contain other,similarly invited persons. In this way, people who are interested insame or similar things and who may have not otherwise met each other,are automatically given opportunities to meet and chat in real time inonline rooms and perhaps benefit from the exchanges. In one embodiment,if an invitation/recommendation confidence score assigned to a giveninvitation (or corresponding recommendation) exceeds a predefinedthreshold, the linking to the chat room or other real time informationalexchange forum (or linking to recommended further search results) isperformed instantly without waiting for acceptance of theinvitation/recommendation. (The invitation/recommendation confidencescore can be one that increases as a function of scores assigned toindicate how on-topic the corresponding invitation/recommendation isdeemed to be, how co-compatible the correspondinginvitation/recommendation is deemed to be, and how interested in thetopic the user is deemed to be. If the confidence score is high enough,the corresponding invitation/recommendation is deemed to be sufficientlyurgent that the user will want to see it instantly. In one embodiment,the user can switch instant showing of high confidence chat rooms and/orinstant showing of high confidence recommended other material on and offas desired and/or change the threshold value needed to trigger instantshowing.)

One of the expected benefits of users accepting invitations to, and/orbeing instantly linked to high confidence ones of chat rooms or otherreal time information exchange forums is that occupants of chat rooms(or other forums) which initially focus upon a first topic will evolve,develop the topic material and eventually migrate their focus to one ormore new topics or subtopics. Migration to new topics or subtopics canresult in the adding of new topic nodes to a hierarchical treecontaining logically linked topic nodes. The tree thus comes alive togrow and evolve dynamically in response to the dynamic and self-evolvingcurrent activities taking place in online chat rooms which run underauspices (patronage) of the tree. Aside from automatically generatinginvitations to currently on-topic chat rooms, the MM-IGS may alsoautomatically generate links to currently on-topic informationalresources such as the latest editorials or blog comments or tweets on arecently emerging topic.

Incidentally, it is to be understood here that when the disclosurementions online chat rooms to which specific users are invited to enter,the disclosure is not intended to be limiting its scope to internetprovided textual chat rooms. Any form of network-provided orbroadcast-provided or multi-cast-provided cross-exchange of relativelycurrent informational content between clustered groups of users canbenefit. This includes live video conferences and the like. Whilerelatively current online information exchanges (e.g., chat rooms) arepreferred, topic nodes of the system may also provide logical links toslower moving (less current) on-topic information resources such asprivate blogs and private forums or list serves to which occupants gainentry to by invitation only. The point being made here is that users whomay have not known of each other or may have not known that they share aconcurrent focus in same or similar content and/or a concurrent interestin same or similar topics are automatically identified and areautomatically clustered together in a topic space so that commonon-topic information they posses (if any) can be conglomerated and sooptionally they can be invited to join with each other in some form ofmachine-assisted current cross-exchange of informational content. Whileinvitation into an online forum is one outcome in accordance with thepresent disclosure, it is also within the contemplation of thedisclosure to independently or supplementally provide recommendationspointing to new online content that corresponds with a topic of currentinterest to the user, where the new online content is likely to becontent that the user has not recently considered.

Once again, for sake of simplicity in this introductory summary, it isassumed that single users are each privately positioned in front oftheir personal computing devices (e.g., laptop, palm-top, PDA,3G-cellphone, etc.) and interfacing with a network (e.g., the internet)via that one device and reviewing online informational content and/orprivately stored informational content. In such a case and according toone embodiment, so-called Local Activities Monitoring Service(s) (LAMS)software is provided in and executes in each user's on-network and localautomated data-processing machines (e.g., client computer). The LocalActivities Monitoring Service(s) (LAMS) predominantly executes in thebackground as a benign form of spyware. The LAMS automatically detectsone or more on-display specific content areas of current focus by thelocal user and/or other portions of content that the user appears to befocusing upon, (e.g., audio output) during a given stretch of time. Thespecific stretch of time can vary from user to user because some userstend to move quickly through large volumes of content (e.g., many webpages visually scanned per minute) and other users tend to step moreslowly through web or other informational content; perhaps reading justa few paragraphs on a same web page over the course of 5 minutes. In oneembodiment, behavioral trend determining services are provided either inthe LAMS or in the MM-IGS or in both for automatically determining thespeeds at which specific users intake different kinds of content andalso the speeds at which the users react emotionally or otherwise to theintaken content. The determined speeds are recorded in so-called PEEPfiles. For example, one user may laugh out loud instantly to a funnycartoon he sees on a web page as he scans through many pages in a singleminute. Another user may take several minutes to digest and become angryabout some upsetting story she read on another web page (showing herreaction by for example silently frowning). Each user tends to have hisor her own personal style for intaking content at a personal intakespeed and for reacting to it (at a personal reaction speed), as well astending to have their own personal styles regarding how they exhibit orexpress their reactions to the content. So Personal Emotion ExpressionProfiles (or PEEP's) are developed over time (by local and/or remotetrending services) for each user and used to determine the appropriatestretches of time over which each user's local activities are to begauged. In one embodiment, PEEP's include a minimal focus persistencetime specification that defines a minimal amount of time that the givenuser is required to be detected as focusing upon corresponding contentbefore a corresponding CFi record is recorded for the focused uponcontent. Content that is focused upon for less than the PEEP specifiedminimal focus persistence time is ignored in that embodiment and acorresponding CFi record is not recorded for it.

Incidentally, the term “benign spyware” as used above and elsewhereherein is a bit of a misnomer because conventional spyware seeks to makeits presence unknown to the spied-upon user and/or spied-upon program.By contrast, the benign spyware discussed herein generally makes itspresence and persistent activities known to the spied-upon user and/orhis programs, by for example, a blinking “monitoring on” warning beingpresented on the user's screen. In one embodiment, the user can elect tohide the warning during a session. It is to be understood then, that useof the term, “benign spyware” herein conveys something other thanconventional spyware where the latter seeks to conceal its presence fromthe user.

While the benign spyware is busy detecting and identifying the specificcontent that its local user is focusing attention on and recording thesame (as a Current Focus information or CFi data), the encompassing LAMSis also working in the background to automatically detect one or moreindicia of current emotional engagement with, or reaction to, thefocused-upon content by the local user. This automated detection ofemotional involvement/reaction may be based, for example, on currentmachine operating activities of the user (e.g., mouse use, keyboard useetc.) and/or on current biometrically detected states of the local user(e.g., increased heart rate, increased breathing rate, increased depthof breathing, increased fidgeting, unusual skin blushing or paleness,up-tilted head and diverted eyes while listening to audio, etc.). TheLAMS automatically attaches time stamps (and optionally, geographiclocation stamps) to each detected and to-be-reported activity (each itemof Current Focus identifying or indicating data, or CFi data for short).The detected and to-be-reported activities may be single or compoundones. Examples of single activities might be that the user has beenfocusing his or her eyeballs (pupils) on the upper left quadrant of theweb page for the past one minute or that the user vocalized a sigh overthe last 2 seconds. A compound report may indicate that the user justlaunched a search engine search with certain keywords and at the sametime the user's heart rate had increased substantially. Cause and effectare not always concurrent though. Chronological spacings between the twomay be indicated for certain users based on their PEEP's and/or otherdeveloped profiles. The collected and time-stamped report information(CFi data) can be used for automatically determining what collectedpieces of reported user activity probably correlate with other ones(strongly cross-correlate). The collected and time-stamped reportinformation can be ultimately used for automatically determining whethertwo or more users have sufficient concurrency with regard to same orsimilar focused upon content and/or with regard to same or similar topicof interest probably on their mind, etc., so as to justify inviting theminto a same chat room. If the detected degree of attentive focus on aparticular portion of available content and/or if the indicated currentemotional involvement with or reaction by the user to that focused-oncontent output is scored to be above a predetermined threshold, the LAMS(Local Activities Monitoring Service) may automatically generate andstore in a buffer one or more Current Focus identifying and/orindicating records (CFi's) where the latter data objects contain datarepresenting the collected physically-based information (about currentfocused upon content, current biometric behavior, etc.). The CFi's arelocally stored by the LAMS in the client machine and then made availablefor collection (uploading) by one or more on-network Remote ActivitiesMonitoring Services (also referred to as an AARMS) of the MM-IGS system.(In one embodiment, rather than deciding on its own which useractivities warrant being reported to the MM-IGS, the LAMS records allactivities as buffer-stored CFi's and lets the MM-IGS (the remotematch-making and invitations-generating system) sort through theinformation to determine what might be relevant and what not so relevantfor match-making or other purposes.) The AARMS typically executes on oneor more remote servers, where the servers are located either at ageographically local data center or at a far away data center. Datacenters may be interlinked to form a network interconnected, dataprocessing cloud that provides automated match-making andinvitations-generating services (or other services such as that ofmaking automated further research recommendations to users of the MM-IGSsystem).

Uploaded CFi's from different users are automatically parsed in theAARMS to determine which CFi-contained first data of a given user is tobe merged with other recent CFi-contained data of the same user, if atall (and optionally on a weighted basis), so as to provide a morecomplete and meaningful sampling of current user activities forunderstanding what content the given user is most likely focusing his orher attention on and what biometric reaction data most likely correlateswith the content and with cotemporaneous user activities. As indicatedabove, for some fast-paced users, a single CFi record or snapshot ofcontent taken over say, a 3 second stretch of time may be sufficient fordetermining degree of substantial focusing of attention on correspondingcontent and biometric reaction data that correlates to it (because thisuser tends to read and react quickly). For other users, a plurality ofCFi records or multiple sampling snapshots taken over say, a 10 minutestretch of time may be deemed to be more appropriate because this otheruser tends to intake content more slowly (especially if it is for adifficult subject area) and/or to respond with additional user activity(e.g., a follow-up search engine use) more slowly and/or to exhibitbiometrically detected reaction to the same more slowly. The automateddetermination of which CFi snapshots (or parts of snapshots) to mergewith others can vary with time of day, current user mood (e.g., is thegiven user sleepy, upset, etc.?) and/or topic (e.g., is the user readinga dense science article or light fiction?). Since each user can bedifferent, in one embodiment, a personalized set of adaptivelymodifiable knowledge base rules are stored in one or more profiles ofeach user (for example, in local and/or remote PEEP's of the given userand/or in a personhood defining CpCC profiles of the user, which CpCCpdata structure will be detailed below.) A simple example of a CFI's datamerging rule might be: IF time=late_evening and topic_type=complex andmood=groggy THEN merge CFi data over time_stretch=15_minutes; IFtime=early_morning and topic_type=simple and mood=caffeinated THEN mergeCFi data over time_stretch=90_seconds; ELSE merge CFi data over defaulttime_stretch=3_minutes. These personalized CFi data merger rules(knowledge-base rules) may be periodically adaptively changed as thesystem learns of each given user's personal traits and/or as each user'straits change over time.

The uploaded and optionally parsed and merged CFi-provided data itemsobtained from each of the different users are then automaticallycompared to that of other users (or against composite data of ongoingchat rooms) in the MM-IGS for purpose of matching with one another(user-to-user match-making or clustering) and/or for purpose of matchingwith predefined chat rooms (user-to-room match-making). In oneembodiment, closeness of matching or closeness of clustering of users toone another and/or to available rooms is expressed as a machine-utilizedco-compatibility distance between users, where more closely matchedusers are deemed to be less distant from one another in aco-compatibility space and thus are deemed to be closely clustered toone another for purposes of being automatically invited into a commonchat room. In other words, when data gleaned from the respectivecollected Current Focus information records (CFi's) of two or more usersindicate a substantial match with regard to content of currentsignificant focus and/or with regard to topic of concurrent interest; orwhen the collected Current Focus information records (CFi's) of a givenfirst user are found to substantially match the content-related focusand/or topic-related attributes of a preexisting chat room by an onlinematch-making service, the same (or another) online service furthercompares Current personality-based Chat Compatibility profiles (CpCCp's)of the to-be-joined users (or of the to-be-joined first user and of theaveraged members in the potential chat room to which the first user maybe invited) to thereby determine if the personalities of theto-be-joined plural users are sufficiently compatible with one anothersuch that they may beneficially (as they see it) exchange information ina common chat room regarding the material of common concurrent focus. Ifyes, the user(s) having the identified and currently common focus onsame or similar content and/or having the same or similar topic ofinterest currently on their minds, are automatically invited to join ina system-spawned chat room or to exchange information using anotherreal-time and system-supported information exchange mechanism (e.g., alive video web conference or a live voice only conference, etc.), wherein one embodiment the invitations are sent to users who also havecurrent personality-based co-compatibility for chatting with each other.While personality-based co-compatibility may be one attribute tested forprior to inviting users to join into a live chat room, it is within thecontemplation of the disclosure to generate invitations that arefiltered on the basis of other co-compatibility factors such as level ofproficiency in a given topic or reputation regarding a hierarchicallycategorized subtopic within a hierarchal tree having predefined domainnodes, topic nodes and subtopic nodes, etc., as will be detailed below.

Incidentally, throughout this disclosure reference is made to averagedor median or other statistically computed attributes of rooms. In thisregard it is to be appreciated that different users may be continuouslyentering or leaving a given room at relatively fast pace, particularlyin the more popular chat rooms of the system. As such the instantaneousaverage or other statistically computed attributes of the room can betheoretically changing very fast. It may consume too much of systemresources to constantly keep track of the instantaneous average orinstantaneous other statistically computed attribute(s) of each room. Inone embodiment, running averages or the like are recomputed forsuccessive and chronologically spaced apart time windows. The widths ofthe windows and the spacings may vary from room-to-room, or topicnode-to-topic node or domain-to-domain in accordance with systemmaintained knowledge-base rules. In one embodiment, each chat room'sattributes are deemed to be frozen in time for regular intervals; suchas frozen in each one of successive 5 minute stretches whose statisticswere computed over a window covering, say, the last 2 minutes; as frozenin each of successive 10 minute stretches whose statistics were computedover the last 4 minutes, every 15 minutes as computed over the last 5minutes, etc., even though users may be constantly entering and leavingthe room. The time points at which new room attributes are recomputedand frozen into place may be referred to herein as attributecheckpoints.

In one embodiment, invitations to join one or more chat rooms (or tojoin other forms of real-time or non-real time informational exchanges)appear on a side area of each user's computer screen in the form, forexample, of incoming and enlarging radar blips, dots, growing bubbles,etc. or as otherwise displayed icons. The positions, shapes, sizes,colorations, enumerations, etc., of these icons may be fixed or they maychange. The icons may be structured to indicate what on-screen contentof current focus they belong to, and/or what general topic they belongto. Alternatively or additionally the icons may be structured todynamically indicate (e.g., by temporarily glowing) that they logicallybelong to certain on-screen content when the user hovers a mouse cursorover the content. The invitation icons may be structured to indicate howstrongly they correlate to the user's current content area of specificfocus or current topic of interest and/or indicate how strongly the chatcompatibilities of other invitees correlate with chat compatibilitypreferences of the user. In one embodiment, invitations to join one ormore chat rooms (or to join other forms of real-time informationalexchange) first appear as tiny, perhaps semi-transparent and slow movingdots moving in from opposed edges of the user's screen (or window)toward a central area of a top or side banner. As they move inwardly, ifthey indeed continue to do so, they may grow in size, in degree ofnontransparent coloration, and also in degree of on-screen agitation ormovement thus becoming larger and more noticeable centralized bubbles (adisposition that represents being at the center of a hypothetical radarscope). This happens as the local user's current point of focus and thelocal user's current topic of interest (inferred) and the local user'scurrent co-compatibility converge with those of the invitation's chatroom or vise versa. On the other hand, if the user's focus on contentdiverges away from that of the invitation's chat room or if the user'sapparent topic of interest moves away from that of the invitation's chatroom, or vise versa, the corresponding bubbles reverse direction andthey stream away from the center and revert back to less colorful ones,less agitated and sidelined ones that ultimately disappear off of theperipheral edge of the screen or window (beyond the recognizable eventhorizon from which they emerged). In one embodiment, each of incomingradar dots morphs into an enlarging image of one or more animatedtalking (silently talking) heads or faces or avatars where the speed oftalking or other movement by the avatar heads indicates an attribute ofthe invitation such as urgency or relevance of the invitation to onscreen other content. The talking heads may wear hats and/or labelsindicating their related topic and/or name of associated chat room. Ifthe user indicates partial interest in the invitation, by for examplehovering a mouse cursor over the invitational image (e.g., talkinghead), a speech balloon with a snippet of current chat room content mayappear and/or a vocalized version of that snippet may be output from theclient machine's sound system.

If the user accepts one of the invitations (e.g., dancing bubbles,franticly talking but silent heads, etc.), by for example mouse clickingon an invitation-offering icon or otherwise gesturing acceptance of thecorresponding invitation, a corresponding chat room (e.g., a chat windowframe) is automatically opened on the user's screen, where the chat roomis populated by co-compatible other users such as by currentinvitation-accepting other users. In this way, two or more co-compatibleusers such as the above exemplified users who were simultaneouslyreading a same article in Celebrity Sensations Magazine (fictitiousname) in isolation can be united online with one another substantiallyinstantaneously with the understanding that they are interested in asame area of focus if not also in a same topic of interest and that theyhave been deemed to be co-compatible personality-wise and/or otherwisefor chatting with one another about the content material and/or topic ofcommon interest based on a machine-automated matching of their currentchat compatibility preference profiles (CpCCp's and/or optionalDsCCp's—which are topic related profiles described below) by acentralized online matching service.

While the above teaches an in-the-background and thus user transparentsystem for generating invitations, it is within the contemplation of thepresent disclosure to allow users to explicitly request invitations. Inother words, a given user may highlight certain in-web-page content;right click his or her mouse and pick an option (in a pop-out menu, notshown) that asks the system to find matching chat rooms for thehighlighted content and to invite the given user into at least onepersonality-wise co-compatible room among the matching chat rooms. It isfurther within contemplation of the disclosure to allow users toexplicitly search for chat rooms under specific hierarchy nodes of thesystem where the searched for chat room meets explicit search requestsof the user. For example, the user may explicitly request an invitationto a chat room under the domain “sports” and topic “soccer” where otheruser “Sam” is already a participating occupant inside that chat room. Inother words, if users want to be explicitly involved in the decisionmaking of which rooms they get invited into, they can. More generallythough, the invitations generating process is intended to occur in thebackground by autonomous machine operations and without direct(explicit) user participation most of the time so that the user canunobtrusively go about with his or her routine content browsingactivities and so that the user may be occasionally surprised (e.g.,once every 15 minutes) to discover that the system has magically (andautonomously) located a chat room where other people are discussingessentially the same topic the user is studying on his or her localcomputer. The user is also surprised to discover that magically, thepeople in the chat room (if entered, if the invitation is accepted) areof the civility and/or proficiency that the given user prefers for thistopic. Of course, none of this happens by magic but rather by a seriesof background machine-implemented processes as is detailed herein. Inone embodiment, each user can turn off the invitations generating systemfor a predetermined time length (e.g., one hour, one day, etc.) if he orshe finds it annoying and can change their minds and turn it back on atany time they want. Moreover, each user can ask the system to provideinvitations at a faster or slower rate as fits the mood of that user.(In one embodiment, users must be subscribed to a premium service ifthey want the invitations presentation rate to exceed a predefinedlimit.) In most embodiments however, users cannot explicitly force theirway into a given chat room or other online forum running under auspicesof the MM-IGS system. They must be invited into the chat room by thesystem. One reason is that other already participating occupants in thatroom may not want more new corners (due to room population limits) ormay not want that specific newcomer (due to personality conflicts forexample). Additionally, in one embodiment, when a user explicitlyrequests an invitation, the user does not need to be focusing upon anycontent at all. Instead the user may have already developed apersonalized co-compatibility profile (e.g., a CpCCp as will bedescribed below) which by itself allows the match-making andinvitations-generating system (MM-IGS) to locate at the time of request,co-compatible other people with whom the first user will more likelythan not enjoy conferencing with online about no specific initial topicat all. Closely co-compatible users who request such a topic-lessinvitations are automatically clustered into a catch-all chat room withother users where profiles of the invitees indicate they are highlylikely to be co-compatible for such open ended conferencing. By way ofexample, they may wish to confer generally about current events.Eventually, the online conference may evolve towards focusing upon aspecific topic, in which case the catch-all chat room they joined may bemigrated towards a specific topic node as will be described below.However, the point is that the MM-IGS system can be used toautomatically bring together people who are chat-wise co-compatible toconfer about no specific topic or content at all.

In one embodiment, the centralized online match-making andinvitations-generating system (MM-IGS) operates as a distributed cloudcomputing environment wherein workloads are distributed amongst pluralservers and/or data centers based on resource availability and servicedemands by local user populations. In one embodiment, current chatcompatibility preference profiles are automatically updated in a datacenter with which a user's client machine currently interacts, themodification to the chat compatibility preference profiles are timestamped, and then the time stamped modifications are propagated in thebackground through the cloud to be included in shadow copies maintainedat other data centers of the user's chat compatibility preferenceprofiles. If a user's home default data center is unable toappropriately service him or her for any reason (e.g., power outage, toofar away, too overworked, etc.), the user's client machine is redirectedto another data center that contains a relatively up-to-date copy of theuser's chat compatibility preference profiles. That alternate datacenter then provides appropriate match-making and invitations-generatingservices in place of the home default data center.

In one embodiment, current chat compatibility profiles (e.g.,personality related CpCCp's) are computer readable digital data files(each accessible by the corresponding logged-in user and partlymodifiable by the respective logged-in user) that contain demographicsinformation about that local user and preference information specifyinggenerically the kinds of other users which the local user may or may notwish to connect with at the present time for chatting or other forumlike informational exchanges; i.e. blogging, twittering, etc. Thepersonality related compatibility profiles (CpCCp's, PEEP's) may alsocontain adaptively changeable knowledge base rules indicating howuploaded CFi's are to be parsed and/or merged. In one embodiment, thelocal user's co-compatibility preferences may be automatically changedbased on detected mood of the user, surrounding environment (e.g., work,home, coffee shop), current date (e.g., a special holiday for the user),passage of time, accumulated trending information, etc. and thus in oneembodiment the remote match-making service uses monitored useractivities and user surroundings to determine the user's mood or otherprofile selecting attribute to automatically select an appropriate CpCCpmatching that current mood and/or other preferences-determiningattribute. The system also adaptively changes individual knowledge baserules for personality and/or topic co-compatibility processing based onaccumulated trending information. The current chat compatibilityprofiles (e.g., CpCCp's) of one embodiment further include reputationfiles or pointers to such files where the corresponding reputations areones that are built over time for the local user by votes (e.g.,biometrically inferred votes or explicit votes) cast by other onlineusers. The current chat compatibility profiles (CpCCp's) of oneembodiment further include credential files or pointers to such fileswhere corresponding credentials (including those indicatingproficiencies for specific topics or subject areas) are ones that areinitially declared by their users but can afterwards be validated orinvalidated by system operators and/or by challenges or affirmations byother users of the chat rooms spawning system. CpCCp's may furtherinclude identities of a user's favorite topics when in a given mood.These identified favorite topics may be used to better guess at what theuser's current topic of interest is (not to be confused with currentarea of focus) as will be described below.

In one embodiment, one or more of a user's current area of focus (CFi),current mood (Cm) and current voting intent (CVi) are automaticallyinferred at least from biometric data obtained in real time from thelocal user, but could additionally be inferred from other informationcombined with the biometric data such as time of day and surroundingenvironment (e.g., type of background music, its volume, its beat,etc.). The utilized biometric data may be obtained from visual scanningof the user's face (e.g., detecting grimaces, eyebrow lifts, or otherfacial expressions) and/or from mechanical detection of the user'ssitting posture (i.e., fidgeting) and/or detection of the user'spulse/heart rate, breathing rate (CO2 exhalation detection), depth ofinhalations and/or exhalations, galvanic skin response, hand gesturingor the like. Thus if a user is smiling and has eyes wide open, such mayindicate a high degree of satisfaction with what the user is currentlyfocused upon on the user's local screen (or with what is otherwise beingperceived by the user through a user interface of a local dataprocessing device, i.e., a client computer). On the other hand, if auser is detected to be grimacing and gesturing wildly and breathingrapidly and shallowly, such may indicate a high degree ofdissatisfaction or anxiety with what is currently being focused onthrough viewing of the screen and/or through other user interface means.The specific meaning of biometric data gathered from a local user mayvary from user to user, from one surrounding environment to another(e.g., work versus home), from culture to culture (e.g., in somecultures, shaking of head from side to side does not mean disagreement),and so forth. Accordingly, Personal Emotion Expression Profiles (PEEPfiles) which may include translation data and/or biometric dataprocessing rules are formed, stored and used to determine what thebiometric data collected from a given user at the instant or over astretch of time probably means regarding each local user's cognitivestate. PEEP's may be stored locally in the user's client machine and/orremotely in an in-cloud data storage facility. Automatically inferredguesses of what the local user's current interest is (physical focusspot plus mental topic selecting state) and/or what the local user'scurrent conscious or subconscious voting intents are, are automaticallygenerated and respectively recorded in uploaded data objects such asCurrent Focus identifying records (CFi's) and Current vote indicatingrecords (Cvi's). Incidentally, CFi's do not have to be generated fromone same client machine. A local user can have a plurality of automatedmachines arrayed around him where one machine is watching head and eye(pupil) movements and reporting those to the cloud via a first stream ofuploaded CFi's, a second machine is watching posture changes andreporting those to the cloud via a respective second stream of uploadedCFi's, a third machine is watching what content is being made availableto the user (through the third machine itself and/or through action ofone or more other machines or devices) and reporting those to the cloudvia a respective third stream of CFi's. In one embodiment, yet anothermachine watches or otherwise monitors the biometric sensing devices inits locale to determine which if any user the other sensing devices aremonitoring and reports as to the same and the respective machineidentification numbers to the cloud. As will be seen, in one embodimenteach CFi (FIG. 2A) is time stamped and location stamped and machine IDstamped. The MM-IGS (e.g., in-cloud service) can collect these variousstreams and merge them according to closeness of time and locationstamps. In one embodiment, the CFi data generated by each machine ordevice is accumulated in the local machine's buffer and held there forautomated background gathering (e.g., uploading) by an on-network clientwatching service (e.g., an AARMS server) as bandwidth permits. Since theCFi's are time stamped, they don't have to be uploaded at the instantthey are generated. All this generation and accumulation of CFi'stypically executes transparently in the background so the local user isgenerally unaware that this machine-implemented activity monitoring andoptional activity interpretation processing is going on. The local usermerely goes on with his or her routine activities including that ofbrowsing through and occasionally focusing more intently on currentcontent of interest as seen on one or more screens (not necessarily of asame device, could be TV screen and email screen for example) and/orfocusing on current content of interest as perceived through other userinterface channels (e.g., audio data signals, for example from aseparate radio that independently reports to the cloud regarding whatthe user is currently listening to). In one embodiment, the benignspyware activities are limited to one or more windows or frames ordevices which the user has pre-specified as being open for such benignspying upon at that time (e.g., interest_monitoring is set to and shownas being On). In one embodiment, security locked windows or frames ordevices are automatically excluded from being spied upon. Theopen-for-spying windows/frames/devices may have special blinking icons,or special window border colors/patterns, animation or the likeoperating on them per the user's election so as to thereby repeatedlyremind the user that activities within these windows/devices arecurrently being benignly spied upon. The user may deactivate the spypermissions on one or all windows, frames or devices as desired. In thisway, the user may maintain as private certain on-screen and/oroff-screen information at all times, especially when the user shifts hisor her focus to that private material.

While the above teaches an in-the-background and thus user transparentsystem for automatically determining the probable emotional and/orphysiological state of the user (e.g., angry, tired and hungry), it iswithin the contemplation of the present disclosure to allow users toexplicitly declare their emotional and/or physiological state to thesystem. In other words, a given user may right click his or her mouseand pick an option (in a pop-out menu, not shown) that allows him or herto tell the system about his or her self-perceived emotional and/orphysiological state. He or she may explicitly ask the system to locatechat rooms occupied with other people who are equally emotionallyinvolved with a same or similar topic (e.g., angry over a recent newsdevelopment or joyous about a local sports team winning thechampionship). Of course, when caught in the throws of a highlyemotional state, users in general may not be able to step back,truthfully assesses their emotional state and explicitly declare it tothe system, which is why it is preferable to rely on backgroundcollected biometric data. In one embodiment (as detailed below), thesystem automatically determines when to include current emotional and/orphysiological state as one of the parameters for finding a matching chatroom.

If a user accepts a chat invitation (Cciv) from an online match-makingservice (e.g., from the in-cloud MM-IGS) and the user shifts his focus(mouse, eyeball focus, keyboard focus, etc.) into the corresponding chatwindow or frame then in one embodiment, the inferred meanings of hisinn-chat focal activities become different from those inferred fornonn-chat focal activities. The user's bursts of focused and emotionalengagement with inn-chat transactions are interpreted as implied votesfor the content being focused upon within the chat room window. (Userreactions to system-made recommendations for further research—See FIG.3B—may also be deemed as feedback providing votes.) During an ongoingchat, if one subset of inn-chat users persistently express negativevotes (even subconscious negative votes) against the contributions ofone or more other in-room users, the online match-making service mayautomatically and responsively decide to cleave the one chat room intotwo separate rooms that respectively contain the now-separated warringparties (assuming the users did not provide chat preferences indicatingthey wanted a good fight). Each group is informed that the others haveleft the room. In this way, incompatible chat room participants (e.g.,so-called “trolls”) can be efficiently dealt with (removed from contactwith upset others). Chat room trolls are given the impression they havewon because everyone else appears to have left the room. Negativereputations are automatically built up over time about the trolls basedon repeated negative votes cast by numerous other users, especially ofother users who have established good reputations. In this way thesystem can automatically build up reputation profiles for differentusers over time based on the reactions of other participants.Reputations may vary as a function of topic of discussion or subjectmatter or detected current mood of the user.

In one embodiment, if users search on same or similar search termsthrough a same search portal (e.g., the Google™ web search page) and thesearches are initiated within a prespecified chronological distance formeach other (e.g., 5 minutes or less apart) and/or the users are within aprespecified geographic distance from each other (e.g., 50 miles or lessapart), then invitations are automatically sent to those users to chatabout their search results irrespective of what topic the users areactually thinking about. In another embodiment, personality wiseco-compatible users who perform such searches are clustered together andthe invitations are sent to the clusters to join respective chat rooms.Personality co-compatibility may be determined through use of CpCCppersonhood files as shall be detailed below.

Invitations into real time online chat rooms are not a necessary part ofall embodiments of the system disclosed here. At least in one embodimentit is sufficient that further research recommendations are autonomouslymade by the system to the user based on content the user is detected tohave been apparently focusing upon.

Other aspects of the disclosure will become apparent from the belowdetailed description.

DETAILED DESCRIPTION

FIG. 1A is a block diagram of an automated user-watching,user-activities reporting, activities analyzing, user-to-usermatch-making and chat room spawning, chat room migrating system 100 inaccordance with the present disclosure. Major components include clientcomputers 115, 125, 135, etc. respectively located at a plurality ofseparate user locations 110, 120, 130, etc., and a networked servercloud 150 to which the local computers 115, 125, 135, etc., operativelycouple by way of electrical/fiber cables, wireless interconnect or otherappropriate communication means. Within the cloud 150, one or moreservers (not shown) provide a number of services including an Access andAccessible-Resources Monitoring Service (AARMS) 150 a, a topic andDomain Look-Up Service (DLUX) 150 b and a user-to-rooms Matching Service(MS) 150 c. There are yet other in-cloud provided services including aChat Rooms Management Service (150 d, shown below database(s) 151) andothers that will be detailed below. (See also briefly FIG. 4A.) Thecloud 150 may include geographically distributed and separately powereddata centers having fully or partially overlapping service capabilities.(See FIG. 4A again.) Accordingly if one data center becomes inoperabledue to power outage, etc. or one data center becomes overwhelmed withtoo many service demands from a surge in current user population, otherdata centers may step in to absorb the work load.

The local client computers 115, 125, 135, etc. of FIG. 1A may be desktopunits, laptop units, hand-held devices (PDAs), third generation cellulartelephones, or the like. Specific hardware available within each clientmachine (e.g., GPS location indicators, RFID tags, wireless networkinterconnect circuits, etc.) may vary from one local computer to thenext. However, each local client machine (e.g., client computer)generally has some means for remotely connecting to the server cloud150, some means for visually and/or otherwise outputting informationalcontent to its local user (e.g. 111, 121, 131, etc.) and optionally somemeans for receiving input from the local user such as through a localkeyboard (e.g., 111 k, 121 k, etc.), a local mouse (e.g., 111 m, 121 m,etc.), a local microphone (only one shown at 129 but there can be pluralmicrophones at a user site) and so forth.

The local client computers: 115, 125, 135, etc., each also includesappropriate client software 105, 105′, 105″, etc., that is installed inthat computer by one or more means including but not limited to:insertion into the local computer of a compact disc (CD) that containsat least part of the client executable software 105 and/or bydownloading of at least part of the executable client software 105 intothe local computer through use of manufactured instructing signalstransmitted from the server cloud 150. As will be explained in moredetail below, the loading-in of part or all of the client software 105transforms the local computer into one or more altered states whereinthe altered computer operates at least part of the time as an automatedgenerator of Current Focus identifying records (CFi's), as an automatedgenerator of Current Vote indicating records (Cvi's), as a receiver ofchat room invitation records (Cciv's) and/or as an automated displayerof radar-like invitation blips that represent received ones of theCciv's. The client software 105 may comprise a plurality of componentsincluding, but not limited to: a Local Activities Monitoring Service(LAMS) 105 x. In one embodiment, the LAMS 105 x includes an automatedcurrent focal point detector module 105 a (a CFid, shown elsewhere inFIG. 1A) and a current vote detector module 105 b (Cvod, also shownelsewhere). The client software 105 may further comprise a radar-likeinvitations display means (Iv-Disply) 105 c for displaying invitations(e.g., in the form of silently talking heads, spinning tops, in-flyingairplane silhouettes, etc. that appear on the user's screen—see FIG. 1D)and for displaying their respectively associated interest domain andtopic coefficients as well as their user co-compatibility coefficients(see briefly 117 b of FIG. 1D). The locally installed copy of the clientsoftware 105 may cause the transformed client machine to maintain itsown copy of a user browsing history 105 d or it may link to, andsupplement, an already present browser history in the local computer115-135. In one embodiment, the supplementing information indicates alevel of emotional engagement or biometrically indicated interest by theuser for the correspondingly focused upon informational content outputby the same or another local client machine. In the same or anotherembodiment, storage of one or more of the user's internet browsinghistory (105 d), the user's search tool input history (105 e) and theuser's chat room participation history (105 f) occurs in the cloud 150,where in-cloud service modules (described below) can make use of thisuser's historical information (105 d-105 f) as well as making use of acloud retained, Personal Emotions Expression Profile (rPEEP). In oneembodiment, a history 105 g of the user's keyboard, mouse and/or userinput device usages is also kept. For example, history 105 g may recordthe user temporarily highlighting a specific line of text, or zooming into better view a specific piece of content and/or copying a specificpiece of content to the client machine's clipboard. These varioushistories and other records may be used to make automated determinationsregarding the user's probable frame of mind, including what topic theuser is probably thinking about, how emotionally engaged the user is inthat topic and whether the emotional engagement is of a kind (be itpositive or negative) that indicates an automated search for acorresponding chat room should be initiated on behalf of the user.

User focus and/or interest in a particular item may be indicated by avariety of mechanisms including those disclosed in the here incorporatedU.S. Pat. No. 5,890,152 (“Personal feedback browser” by J. Rapaport etal). In other words the interest indicators may comprise or may befunctions of an amount of time spent by a given user in viewing aparticular on-screen article, time spent scrolling through the article,time spent moving a cursor or other location indicator through thearticle, number of mouse clicks on items within the article, amount ofhighlighting of various parts of the article, and so forth. Scroll rateand mouse agitation rate may also be used as indicators of current levelof interest. Time spent apparently listening to related audio contentmay also be used as an indicator of current level of interest.

Each user is different and thus may indicate heightened interest in oneform or another of informational content that is being displayed and/orotherwise output to the user by his local machine by means of adifferent set of local user activities. Accordingly, in one embodiment,the local client software 105 includes a local Personal EmotionExpression Profile (L-PEEP) 107 which correlates different ones oflocally expressible and detectable physical activities of the user withdifferent kinds of interest and/or emotional indications, be theynegative, positive or neutral. The meanings of detected user state mayalso change as a function of user mood or user surroundings.Alternatively or additionally, the Remote Client Access andAccessible-Resources Monitoring Service (AARMS) 150 a in the cloud 150may link to a client account database that stores an online or remotePersonal Emotion Expression Profile (rPEEP) where the latter is maderesponsible for carrying out, or for supplementing the correlations madefor different ones of locally expressed and detected physical activitiesof the user with different kinds of interest or emotion indications. Inone embodiment, standardized interest indications are established by theonline match-making service such as a spectrum of interest indicationsspanning from substantially not engaged to fully engaged and such asfrom substantially negatively disposed to substantially positivelydisposed when used for representing level of emotional disposition. Inone embodiment, a neural network adaptive model or the like includestrend and erratic departure detectors and is used for determining bestguess correlations between locally detected indicia of user focus and/oremotion with otherwise indicated levels of focus and/or emotionaldisposition. In the same or an alternate embodiment, a statistical modelis used for scoring on an ordered probabilities basis, correlationsbetween locally detected user activities and/or biological states andcorresponding states of the user's mind (e.g., engaged versus bored,happy versus disappointed or upset, etc.). In one embodiment, the neuralnetwork adaptive models and/or statistical models are used to adaptivelyalter knowledge base rule sets for individual users where the knowledgebase rule sets dictate how various pieces of information will becombined and processed.

In terms of a more concrete example, reference is now made to PEEPrecord 107 of FIG. 1E. This Personal Emotion Expression Profile (PEEP)record can be fully stored in one or both of the user's local clientmachine (e.g., 115) and in the cloud 150 or its functionalities can bedistributively stored, partially in each. Most people have favored bodylanguage expressions (or “tells” in a poker player's parlance) by way ofwhich they tend to signal their state of mind even though they may notverbally express the same. Of course, a stone faced professional pokerplayer who intentionally hides his “tells” with sun glasses, etc., maynot be able to beneficially use the here described system. However, mostusers will keep their faces substantially exposed and willsubconsciously signal their internal state of mind by various bodylanguage clues such as how rapidly they blink their eyes, how long theystare at a particular location, by changes in eye pupil dilation, by howtightly they purse their lips, how rapidly and/or deeply they inhale andexhale (or how long they hold an inhalation), how often they sigh and/orshrug or slump their shoulders (if at all), how long they pause betweenusing mouse or keyboard, how they twitch various facial muscles, and soon. A great deal of literature on body language cues is availableincluding in the realm of so-called poker “tells”. As will be detailedbelow, various means for observing the user's body language may beprovided in, or coupled to, the client machine (or operatively coupledto the cloud while being located at the user site) where these means mayinclude but are not limited to having one or more web cameras (e.g.,116) that constantly watch the user's body, including his face, hiseyes, his hands, etc. for the purpose (among others) of reporting bodylanguage tells to the cloud. Operative coupling between the webcamera(s) and data processing hardware within the user's primarycomputer 115 may be provided in any of a variety of ways including wiredor wireless couplings. Aside from providing image data to the user'sprimary computer, one or more of the web cameras (e.g., 116) may providesensor settings data such as an indication of one or more angles atwhich the camera is pointed, an indication of a variable focus length atwhich the camera's lens system (if variable) is currently set at, anindication of a variable aperture (if variable) being currently used bythe camera, an indication of a variable spectral filter (if variable)being currently used by the camera, and so on. In addition to or as analternative to the one or more web cameras (e.g., 116) that constantlyor periodically watch the user's body, the user's local machine systemmay include other optical devices (e.g., tracking lasers) that track theuser's eyes for various purposes including for example determining wherethe pupils are pointed to and what the current pupil dilation is and/ordetermining when and how often the user blinks. In addition to or as analternative to the one or more web cameras (e.g., 116), the user's localmachine system may include other head position determining means (e.g.,tracking lasers) that track the user's head positions for determiningfor example as among various user state parameters, how far the user'sface is form one or more content display devices, for determining howoften and/or to what extent the user shakes or bobs his head (e.g., inrhythm to background music), and so forth. Every user tends to beslightly different in how he or she expresses their tells and what thosebody language displays mean. For one person, shaking of the head up anddown may mean agreement while for another, something entirely else.Accordingly, a Personal Emotion Expression Profile (PEEP) isindividually developed over time for every system user. New users mayhave a stereotyping PEEP initially assigned to them. This stereotypingor template PEEP is modified over time as the system adaptively learnswhich body language cues are most telling in given circumstances foreach user. The assigned stereotyping PEEP may be selected based on placeof birth, ethnicity, culture, age, gender, reported education level,and/or other demographic information provided by the user.

In one embodiment, a first table column 196 of the PEEP database record107′ (FIG. 1E) lists the monitored or monitorable biometric parametersas an ordered list with the more preferred (the more telling) of theindividual user's biometric parameters listed first. Not every localclient machine (e.g., palmtop versus desktop computer) can monitor everyparameter. It depends on available monitoring resources. The orderedlist of more and less preferable monitorable biometric parameters (196)is consulted by the local client machine the user is using and a subsetof available resources is selected. Ordering of the list 196 is achievedin adaptive iterations as the system adaptively learns which parametersare better tells than others under varying circumstances (e.g., at work,at home, in morning, in evening, etc.). Success may be determined basedon occasional surveys sent to the user and also on positive feedbackobtained from the user accepting more invitations rather than less whenthe invitations are based on the more telling of the monitorablebiometric parameters.

In addition to ordering the monitorable biometric parameters accordingto which are more telling in given circumstances, the average latencybetween cause and effect are recorded for each in time stretch column197 of the table. some biometric parameter changes may occur long afteran instigating event (e.g., viewing emotion creating content) whileothers may take root soon after. The time stretch needed betweentime-stamped ones of start and stop CFi's may be determined based on theaverage latency times recorded in column 197. The actual time stretchemployed may be varied according to adaptively adjusted expert systemrules provided in a knowledge rule base 199 that may be embedded in eachPEEP record (or stored elsewhere and logically linked to the PEEP). Asknown to those skilled in knowledge rule databases and automated expertsystems, IF-THEN-ELSE statements can be nested one in the other and eachcontaining conditional expressions plus conditionally actionableconsequences. The nesting can be changed, the conditional expressionscan be changed and the data ranges or other data values inside theconditional expressions can be changed. Accordingly a very flexiblesystem is made available for adaptively learning what monitorablebiometric parameters work best (or good enough) for each individual userunder various surrounding conditions, what ranges or trigger limits ofdata values inside the conditional expressions work best (or goodenough) for each individual user, and what nesting of rules works best(or good enough). In one embodiment, before less important other partsof a given PEEP record (e.g., 107′) are processed, a PEEP recordswitching rule (e.g., IF Surroundings=Work THEN . . . ) is automaticallyexecuted so as to conditionally swap in a different PEEP record (e.g.,107.2, not shown) in place of the default PEEP record when certainpredefined conditions are met, such as when it is determined that theuser is at his or her work place rather than at home, that the user isusing a handheld data processing machine (e.g., cell phone) rather thanthe usual desktop computer at home or at work, that the user is notalone, that the time of week is a weekend rather than a weekday, and soon. In this way wholesale changes of PEEP defined behavior can be madebefore finer determinations of user state are made based on in-PEEPknowledge-base rules and/or based on in-PEEP primary physical statedefinitions.

Here are some nonlimiting examples of knowledge base rules that may beprovided in a PEEP record and used for determining via automated meanswhat the user's current emotional state is: (1) IF Heart_Rate increasedby 2% in last 5 minutes THEN increment Anxiety_score by +1, ELSE IFHeart_Rate decreased by 3% in last 4 minutes THEN adjust Anxiety_scoreby −1. (2) IF posture_change shifted weight bearing 20% or moreasymmetrically to one body side more than what average of last hour wasTHEN increment Jumpy_score by +1, ELSE decrement Jumpy_score by 0.5. (3)IF Words_per_minute_read increased by more than 10% overbase_reading_rate_of_current_content_displayer in last 2 minutes THENincrement Interest_score by +1 ELSE IF Words_per_minute_read decreasedby more than 30% below base_reading_rate_of_current_content_displayer inlast 2 minutes THEN increment Interest_score by +2 AND increment CFi'stime stretch by +3 minutes ELSE decrease adjust Interest_score by −0.3.(4) IF eye dilation increased by 10% or more while reading lastparagraph AND same paragraph was reread THEN increment Interest_score by+5 AND increment CFi's time stretch by +2 minutes. (5) IF userinterrupted reading to type notes and then quickly returned to readingsame content and then proceeded to make further notes THEN incrementInterest_score by +10. (6) IF user's eyes tracked paragraph withoutinterruption for more than 1 minute AND Respiration_rate decreased bymore than 20% THEN increment Interest_score by +8 AND incrementConcern_score by +3. (7) IF user read last paragraph uninterrupted ANDeyes dilated AND microphone(s) detected utterance of swear word by userAND user put hands to face and shook face, THEN increment Upset_score by+50. (8) IF user stopped reading (eye sweep stops) and stared intomonitor for more than 45 seconds (thus appearing to concentrate onthinking) AND then user resumed reading with increased Heart_rate THENincrement Interest_score by +10. (9) IF user stopped reading (eye sweepstops) and user quickly changed web site (new URL) and became engaged inactivities unrelated to currently displayed content THEN adjustInterest_score by −25. (10) IF user returned to original web site (oldURL) and user resumed reading same (eye sweep resumes) and user ceasedunrelated activities THEN adjust Interest_score by +25 (to wipe outearlier negative due to newer showing of continued interest in contentof old URL, perhaps due to user re-evaluation of value of that oldercontent). (11) IF user Heart_rate in range of 117 to 123 beats perminute, THEN set Extreme_excitement to True. (12) IF user inhalationdepth is greater than normal by 25% and respiration rate is Regular THENset Deep_interest to True.

In one embodiment, initial knowledge-base rules sets may be hand codedand stored into respective stereotyping or template profiles togetherwith pointers pointing to rule parameters that are to be automaticallyfine tuned by the system over time on the basis of experience with agiven user's behavior. In one embodiment, pattern discovery and/or rulesgeneration are automatically carried out in accordance with Rough Setstheory and/or other expert system knowledge base development techniques.In one embodiment, a combination of automated knowledge base developmenttechniques and hand coded refinement may be used to produce the initialknowledge-base rules sets.

In one embodiment, table column 198 a identifies the mental state(typically expressed as a numerical score by the data processingmachines described herein) that most closely correlates with themonitorable biometric parameter of column 196 for the given individualuser. The correlations can change from person to person, from oneenvironmental setting to another and even for a same user over thecourse of time. Thus these listed correlations are adaptively changed bythe system over time using feedback obtained from user filled surveys,obtained from emotion evoking test content and/or from rate ofinvitation acceptances. In one embodiment, table column 198 b identifiesroom matching keywords that are best employed for that person to findchat rooms having emotional states empathetic to the correlates ones ofthe given user whose PEEP record 107′ is shown. The correlations ofcolumn 198 b can change from person to person, from one environmentalsetting to another and even for a same user over the course of time.Thus these listed correlations 198 b and utilized keywords areadaptively changed by the system over time using feedback obtained fromuser filled surveys, obtained from emotion evoking test content and/orfrom rate of invitation acceptances. In one embodiment, each PEEP filemay include an early executed knowledge base rule that swaps out thecurrent PEEP file 107′ and replaces it with another PEEP file (e.g.,107.2, not directly shown) in response to, for example, time of day,primary client machine being currently used by the user, detectedsurroundings of the user and so on. More specifically, a given user'snormal reaction times may vary as a function of such parameters and bysubstituting in the appropriate PEEP file the system can automaticallymake whole sale adjustments to finer PEEP parameters by first pickingthe context-appropriate PEEP file.

A PEEP database record or file may have a variety of different fieldsfilled with various correlations and/or adaptively changeable rules. Asseen in the example of FIG. 1E, for each class of major body areas thatare to be monitored, there can be plural subsets to be monitored withindividual correlating factors attributed to those subsets. Theknowledge base rules 199 may include rules specifically tailored to themonitored subclasses of biometric parameters (e.g., pulse rate, bloodpressure, oxygen saturation level, etc.).

Referring again to FIG. 1A, the browsing history 105 d (URL's recentlyvisited) maintained by the local client software (and/or in the cloud)may be supplemented by a search engine history 105 e which indicatesvarious keywords that the user has recently used (e.g., over rule-basedstretches of time) in conjunction with use of one or more search enginesat roughly the same time that focus centered on a particular screen areasuch as 117 a within web page 117 and interest was expressed by one ormore machine-implemented means. The keyboarding and/or mouse useactivities history 105 g may be used to determine that the user forexample highlighted certain words or phrases and/or copied them to aclip board, all this indicating that perhaps greater weights should beassigned to the highlighted words or phrases. These highlighted words orphrases and/or utilized search keywords may be used alone or incombinations with other hinting data (e.g., URL's, hidden meta-tags, theuser's personal profiles) to automatically determine the more probableones of possible topics of interest that might currently be on the localuser's mind as he focuses on corresponding content (e.g., 117 a). Thetopic Domain Look-Up Service (DLUX) 150 b in the Cloud 150 may use userhistories uploaded form the user's local machine and/or user historiesalready stored in the cloud 150 to automatically determine probabletopics of current interest of the local user. It is to be understoodthat focal area (e.g., 117 a) and topic of interest are not necessarilyone and the same. For example, one user (e.g., 111) might be focusing ona map of Las Vegas, Nev. because he is an avid poker player and wants tomap out directions for traveling to an upcoming tournament. At the sametime, another user (e.g., 121) might be focusing on the very sameon-line map (same URL) of Las Vegas, but because she is doing a schoolreport about the Hoover Dam and its surrounds. Thus, common contentfound in the area of focal attention does not necessarily mean sametopic of interest. In one embodiment, the system strives toautomatically determine both what content is being focused upon and whattopic of interest is probably on the user's mind in conjunction withthat content as well as the degree of interest in the content and topic,where the determination is to a sufficient level of accuracy, resolutionand/or confidence so that only truly co-compatible users who arethinking about the same or a relatively similar topic will be invitedinto a same chat room. In other words, poker players will meet up withother poker players (e.g., for example to discuss the latestdevelopments in reading other players poker “tells”) and Hoover Damresearchers will meet up with alike researchers in the respective chatrooms to which they are invited even though all may have been focusingon the same common content. In an alternate embodiment, commonality ofcontent being focused upon may be alone sufficient for invitingconcurrently focusing users into a same chat room.

Aside from using the locally stored browser use history 105 d and/orin-cloud stored history of the user's browsing activities (and/or mouseuse activities 105 g) to determine probable topic of interest, automateddetermination of the user's probable topic of interest may be based on alocally stored history of the user's chat room activities (e.g., storedin local chat history file 105 f) and/or in-cloud stored history of theuser's chat room activities, where the latter histories may containinformation about the identities of the chat rooms that the given userhad recently entered into (whether invited or not) and that informationmay include duration of stay in the room, level of contribution to roomcontent and indications of positive or negative reactions by the user tothe contributions of others within that chat room. The latter gatheredinformation can be used to automatically infer certain preferences ofthe client user (e.g., 121). In one embodiment, one or more adaptiveneural networks and/or statistical analysis models are established inthe cloud 150 for each user for determining from a host of inputparameters, that user's current, most probable topics of interest; thatuser's current, most probable emotional state; and that user's current,most probable voting intentions (inferred ones rather than explicitlystated ones). The host of input parameters may include data provided incurrent CFi's, data obtained from the user's most recent or earlierbrowsing, searching and chatting histories and data regarding apparentsuccess of earlier guesses made by the neural network or other models(for example, based on the user accepting an invitation into a chat roomand the user demonstrating satisfaction with the choice, such as by theuser participating for a relatively long time in that chat room). Asalready mentioned, one of the database records that the user modelsperiodically try to tweak based on feedback are each user's PEEP record(107′ of FIG. 1E). The PEEP in turn may determine the stretches of timeover which successive CFi's are correlated to each other (or parsed datafields within first CFi's are correlated to other data fields withinother CFi's, for example content in first CFi's correlated to delayedemotional reaction in later stamped CFi's) so that CFi's are processedaccording to user-specific behavioral trends. Accordingly, when it ismentioned herein that “recent” data is processed for one purpose oranother, it is to be understood that the stretch of time deemed to be“recent” can be variably adjusted for example in accordance with normaltimes and rule-established variances of those normal times as stored inthe given user's currently effective PEEP record.

Another aspect to be recalled here is that the informational content towhich a user is exposed; and to which content he or she may pay more orless attention to (degree of focus); and in which content he or she maytake greater or lesser interest in; and with which content he or she maybecome emotionally involved to a greater or lesser degree; does notnecessarily come all or partially from the local computer (e.g., 115) onwhich the user is performing searches or on which the user isparticipating in chat rooms. The user could be watching a soccer matchon a nearby television set and at the same interacting on his localcomputer (e.g., 115) with a chat room populated by soccer enthusiasts.Or the user could be listening to a nearby radio over which the soccermatch is being telecast. It is the job of the local computer (e.g., 115)to determine what one or more content-providing devices (e.g., TV,radio, computer monitor 117) the user is focusing attention on overPEEP-defined stretches of time and to determine the degree of thatattention (e.g., high, medium or low) and to determine the degree ofinterest that the user is taking in the focused upon content. To thisend, various local range networking schemes such as wireless BlueTooth™or the like may be used so that the local computer (e.g., 115) caninterrogate nearby other content-providing devices (e.g., TV, radio,other computers including XBox™ or other game playing machines) todetermine if they are turned on or not, and if yes to determine whatcontent they are currently providing and/or what their audio volumesetting is and/or how often and how the user is interactivelyinterfacing with them (particularly the game playing devices).Additionally, microphones (soon described) of the local computer (e.g.,115) may pick up noises emitted by these various devices and relaysamples of the same to the cloud 150 for analysis and determination ofwhat specific content the local user (111) is being exposed to. Morespecifically, as mentioned above, the user may be surrounded bybackground music. The background music may be fast paced heavy metalrock and roll or slow paced classical symphony music. These differenttypes of music or even their primary beat may be indicative of the kindof mood the user is in. Also the volume of the music or the rate atwhich the music changes from one type to another (e.g., because the useris fidgeting with the station selection controls) may be indicative ofcurrent user mood. Alternatively, there could be loud machinery noise inthe background or screaming young children which could place the user ina bad mood. Provided on the microphones, on the computer displaymonitor, or separately, there may be room lighting detectors whichdetect the brightness and pervasiveness of surrounding room lighting,where the later is automatically reported to the cloud as beingpotentially indicative of current user mood.

As an alternative or addition to use of BlueTooth™ or the like forinterrogating other local machines and obtaining reports from them, theuser's primary local computer (e.g., 115) may include an RFID detector(radio frequency identification interrogator) that tests for presence ofRFID tags in the surrounding equipment and thus determines the nature ofthe surrounding equipment (and perhaps their distances from the RFIDdetector). This coupled with sound picked up by the microphones, roomlighting detected by room lighting detectors or controls and imagerypicked by the primary local computer's web camera (116) may besufficient for identifying the external content to which the local useris being exposed to and for determining when the local user is directinghis or her attention to that other content-providing device. So tosummarize, although discussion herein centers on content provided by webpages displayed under control of the user's primary local computer(e.g., 115), the present disclosure is not limited to web-page encoded(e.g., HTML, XML) presentations. Content to which the user is exposedand to which he or she may pay greater attention to, take greaterinterest in, and so on, can come from any automatically identifiablesource and the user's primary local computer (e.g., 115) may have meansfor identifying the content produced by that source (e.g., via listeningin with the microphones, via BlueTooth™ interrogation, etc.) and mayhave means for determining when and to what degree the local user (111)is paying attention to that externally provided content and reacting toit. In one alternate embodiment, each external content providing digitaldevice may automatically feed CFi's (wirelessly or otherwise) to theuser's primary local computer (e.g., 115) for uploading to the cloud orone or more of those external content providing digital device mayautomatically feed CFi's directly to the cloud 150 for integration inthe cloud of those CFi's with CFi's uploaded from the user's primarylocal computer. (It will be seen in FIG. 2A that in one embodiment,every CFi has a time stamp 215 d, a sourcing machine identificationstamp 215 b and a location stamp 215 c, thus allowing the cloud tointegrate CFi's produced by different machines but at roughly the sametime and in a relevant neighborhood of the user so as to therebydetermine what content the user is potentially paying attention to.)

As seen in FIG. 1A, a variety of optional biometric data detectingdevices may be attached to, or installed within, each user's localcomputer(s). Each user may have more than one local computer at hisdisposal and each should have a unique machine ID defined under thatuser's name. These ID's are stored in an online user account data store(see UADS 432 of FIG. 4A for example) and can thus be correlated tospecific machine definitions and associated machine behavioral patterns.By way of nonlimiting examples regarding the different biometricdetecting devices, each of client computers 115, 125, 135, etc. mayinclude one or more respective digital video cameras, 116, 126, 136,etc. that are positioned to scan at least the local user's head andfacial expressions (and better yet, at least the upper torso bodylanguage displays). The camera(s) (e.g., 116, and associated software)may be configured to keep track of the user's eyeballs 111 b, how theymove and where they focus, and also to keep track of how wide open theeyes or pupils are dilated and/or how often the eyelids blink. In oneembodiment, the camera(s) (e.g., 116) may emit a short pulsed light inthe IR or other wavelength band that reflects off the user's eyeballs(sclera) and which reflection (including the dark spot of the pupil) ispicked up by photodetectors embedded on the user's screen 117 orelsewhere for determining eyeball position and/or orientation and/orpupil dilation and/or eyelid blink rate. The camera 116 may additionallykeep track of the shape of the user's mouth 111 c including whether itis in a smiling configuration, a grimacing configuration, a lip bitingconfiguration or other; and also the rate at which the lips move if atall. The camera 116 may additionally keep track of the apparent distanceof 111 d between the user's head and the computer screen 117. The user'shead may become enlarged within the camera's scanning frame when theuser leans in towards the screen 117 or shrunken when the user pullsback away. An ultrasonic motion and/or distance detector may be includedto detect and measure movements by the user. In one embodiment, thelocal camera 116 may not only have a first sensor array (e.g.,CCD—charge coupled device) for sensing an image in the visible lightrange, but also a second sensor array for sensing an image in theinfra-red (IR) range. The IR image may indicate facial blushing by theuser and/or rate of exhaling warm air with each breathing cycle (ortemporarily withheld breath), volume of exhalation, and so forth. In oneembodiment, additional cameras may be connected to the local machine todetermine the user's surrounding environment, such as determiningwhether the user is alone or not, whether the user is at home or atwork, the user's sitting posture, etc. This information may be used toautomatically infer the user's moods.

The local client software 105 may use one or more of these or variousother biometric indicators to infer what the local user (e.g., 111) isconsciously or subconsciously thinking (111 a) with regard to material117 a that is being displayed on the screen 117 or otherwise presentedby the local computer and on which the user's eyeballs (his pupils) arecurrently focusing upon (and/or on which the user's mouse cursor isdwelling or keyboard cursor is dwelling upon or highlighting). The localclient software 105 may use the various biometric indicators to alsodetermine how focused and emotionally engaged or not the user is on thatparticular area 117 a and/or what positive, negative or neutralemotional attributes the user 111 is assigning to that focused-uponcontent 117 a by virtue of the user's currently expressed and detectedbiometric and/or other activities (or later detected biometric and/orother activities that are logically associated as effect and cause pairswith earlier content in accordance with the user's PEEP record, e.g.,107 and/or in accordance with other effect and cause pairing data.Additionally, the local client software 105 may use various contextcues, such as by detecting the location of the user via a GPS sensor 111z or other means (e.g., nearby RFID tags, nearby other equipmentdetected by wireless coupling via BlueTooth™ or the like) anddetermining from the identified surrounding location (e.g., at home, inthe office, on the road, alone, in a crowd, etc.) what the probabletopic of the focused upon material is. (Topic and/or topic domain may beautomatically determined by the DLUX service module 150 b which will bediscussed later below.)

Some users' computers may include one or more microphones 129 for notonly picking up voice communications by the user (e.g., 121) but alsofor detecting voice stress patterns in the user's speech and/ordetecting non-verbal grunts or other sounds which the user may make toexpress enjoyment, dismay and so forth. Additionally, the microphone(s)may be used to determine the surrounding environment in which the useris situated. Are there noisy children in the background and/or a barkingdog? Is a TV or radio blaring in the background? What type of music isbeing played? What current broadcast TV show is being watched orlistened to? Alternatively, is the user relaxing at a quite poolside ofa luxury hotel or in a darkened room while sipping a fine wine (whoseodor may be detected by an optional odor sniffing device that reports tothe cloud)? Much can be determined by picking up and analyzingbackground noises and/or odors and/or lighting cues. Knowledge-baserules can be provided in the cloud for analyzing uploaded backgroundnoises, etc., and for determining probable user mood based at least inpart on such background noises, etc. In the case where pluralmicrophones 129 are present, these may be directional ones and used fordetecting the direction and/or location from where a noise came as wellrecording the sound for analysis. It is possible for a verbal utteranceto come from someone other than the primary user, where the primary useris the person closest to the display 127. Plural microphones can be usedto discriminate and ignore unrelated background noises. Also if astartling noise comes from behind or to the side of the user, the pluralmicrophones can detect this and determine that an immediately responsivechange in biometric data (e.g., the user turning away from the screen tolook at the source of the sound) is unrelated to on-screen content.Client software 105′ may include interface components for receiving theaudio signals from microphone(s) 129 and for using these to determinecurrent emotional states 121 a of the user and/or to determine when acurrent emotional state is unrelated to on-screen content. Once again,because emotional expression by each user may vary due for example togender, culture, surroundings, etc. and may vary from day to day, theclient software will often include a local personal emotion expressionprofile (L-Peep, see also FIG. 1E) 107 for that user which indicates tothe software how to interpret various auditory expressions by the useras well as visual gestures and so forth during a current usage period.Alternatively or additionally the match-making service (150 c) maymaintain remotely stored personal emotion expression profiles (rPeep's)for the given user where the active rPeep file indicates to the softwarehow to interpret various auditory expressions by the user and/or visualgestures, biometric input data and so forth so as to therebyautomatically determine current user mood and/or other inferred mentalstates and also to determine the stretch of time over which CFi's shouldbe grouped together to represent interrelated biometric data and thecontent that is being biometrically responded to by the user. Thepersonal emotion expression profile(s) Peep 107 and/or rPeep's (notshown in 1A but can be same as in FIG. 1E) may be adjusted with use ofneural networks, statistical modeling, knowledge-base rules sets, trenddetecting software or the like to adaptively learn how the userexpresses his or her emotions via the various detectable mechanisms suchas auditory, visual, biometric, etc. Correlations and/or rules providedin the PEEPs may be adjusted accordingly. For example, on intermittentoccasions in one embodiment, user surveys or other standardized testcontent that is designed to evoke certain emotions may be presented tothe user and the user's auditory, visual, biometric or other reactionsmay be observed and recorded so as to calibrate and refine the localand/or remote personal emotion expression profiles Peep 107 and rPeepfor that user. (Each Peep 107 is associated with a specific user namewhich should be provided in a log-in session (or the user identificationmay be determined by face recognition software) so that a correct PEEPfile is fetched and updated in cases where more than one user uses thelocal computer. Additionally, PEEPs may be sensitive to surroundingenvironment and the location data obtained from GPS module 111 z orother location detecting/indicating means, for example embedded RFIDtags in surrounding equipment, to adjust inferred mental states of theuser based on surrounding location and artifacts present in thatlocation.) Additionally, PEEPs may be made sensitive to time of day,date during the year (e.g., especially those relating to general publicholidays, cultural holidays, personal birthdays, etc.) such thatdetermination of emotion may vary according to these variables.Additionally, PEEPs may be made sensitive to the apparent topic ofinterest of the user (or type of topic) and/or the general domain towhich the currently focused upon content belongs. This can be done inthe adaptively variable knowledge base rules (e.g., 199). First guess atdomain or type of topic (e.g., serious topic versus light hearted one)may be made based on current URL and the user's declared favorite topicsin his or her CpCC profile (see box 154-7 a of FIG. 1B). The PEEP rules(199) may use the first guess at topic, type of topic and/or domain asan input variable. Later, the system may make a better, more refineddetermination of probable topic based on collected, parsed and processedCFi's. Stated by other words, a given user may demonstrate one set ofbehavioral/emotional expression attributes when dealing with a firsttype of topic, say a serious subject matter (e.g., a personal healthconcern) and the same user may demonstrate a second, very different setof behavioral/emotional expression attributes when dealing with adifferent type of topic, say less serious subject matter (e.g., readingonline jokes involving a fictitious person's to-be-laughed at healthproblems). The URL of the content plus embedded meta-tags may providesufficient information for the system to automatically make a good firstguess determination that the topic is a serious type, not a comical oneand the PEEP rules may then dictate a corresponding interpretation ofthe user's behavior according to the first guess as to the nature of thetopic. Uploaded CFi's (to to-be-uploaded CFi's) are treated (parsed,grouped, etc.) according to CFi treatment actions suggested or dictatedby the PEEP rules (199).

Some users of system 100 may elect to wear a biometric timepiece 111 tpsuch as one shown to appear as a wristwatch on the wrist of user 111.However this biometric time piece 111 tp may be configured not only toreveal the current local time and date (and optionally time instandardized Greenwich Mean Time (GMT) format) but also to perform oneor more of the following: wirelessly relay to the computer the currentpulse rate of the user, relay the current galvanometric skin resistanceof the user, relay strain or tightening of the wrist band which mayindicate flexure of forearm muscles, relay acceleration of the timepiece 111 tp which may be detected by integrated miniaturizedelectromechanical devices (MEM's) and may represent hand gestures andspeed thereof by the user and/or relay a Doppler signal from anintegrated Doppler ultrasound blood flow detector which detects rates ofblood flow in the user's hand, pulse, etc. Additionally or alternativelyother medically related devices and/or methods may be used to pick upfor example the user's current rate of respiration, blood pressure,state of agitation, distribution of weight on weight bearing surfaceswithin a properly configured chair 121 s or sensor-riddled floor mat(not shown) and so forth for the purpose of determining the user'scurrent emotional state. In one embodiment, specially configured chair121 s is further configured to communicate to the local computer 125 theseating posture of the user 121, for example using sensed weightdistributions to indicate whether the user is leaning forward on theedge of the chair or relaxed and leaning backwards on the back of thechair, leaning to one side or the content and/or for how long.Additionally, or alternatively some users may elect to wear specialbiometric measuring clothing, shoes, gloves, etc., which wirelesslyreport to the computer 125 (or directly to the cloud) various aspects ofthe user's external body language and or internal medical state (e.g.,EKG, EEG, etc.). As already mentioned, in one embodiment the displaymounted digital camera 116 may include means for capturing local imageryin more than one optical band, for example in the IR band in addition tonormal visuals captured in the visual (e.g., RGB) band. IR capturedimagery may indicate flows of warm blood to different parts of theuser's face, rate of exhalation of warm air, depth of exhalation, and/orother biometrically related information. In one embodiment, the software105 includes a privacy consent agreement which must be digitally signedby the user before such privacy challenging information is collected andrelayed to the match-making service in cloud 150. Since the numbers andkinds of biometric data gatherers (e.g., 111 tp, 129, 121 s, 126, etc.)can vary from one user computer (e.g., laptop) to another (e.g., thirdor later generation cell phone or personal digital assistant PDA), thematch-making service (150 c) may include software for dealing withvarious permutations of available biometric data gatherers and differentknowledge-base rules (e.g., 199) may apply depending on which biometricdata gatherers are available and being used for reporting on thebiometric state of the user. For example, a same user on one day may beusing his full featured desktop computer with a large array of availablebiometric data gatherers and another day the same user may be using hispotable PDA (or intelligent cell phone or other intelligent mobilephone/device based on appropriate other technologies such as WiFi,satellite, etc.), which intelligent mobile device has a substantiallysmaller number of available biometric data gatherers with perhaps morelimited capabilities. More specifically, the hand held intelligentmobile device may be limited to capturing a low resolution image of theuser's face and to detecting how the hand held device is being grippedby the user, how hard it is being gripped and in what orientation. Thesystem has to make due with this limited amount of gathered biometricdata. The match-making service automatically detects the available(operable) biometric data gatherers for each user session and adaptivelyadjusts its data processing accordingly (e.g., by using knowledge-baserules provided in the user's PEEP record(s), e.g., 199). Biometric datagathering devices may be integrated into the user's mouse or keypad sothat biometric information is automatically detected and gathered eachtime the user's hand comes into proximity with such a user interface(e.g., GUI) device. For example, a mouse may have an IR subsystemembedded on a side surface thereof where the user's thumb normally comesto rest when manipulating the mouse. The IR subsystem detects proximityof the thumb and lights up at that time to pick up the user's pulserate, skin temperature (indicative perhaps of vessel constriction orsweating) and other parameters. Skin resistance at the thumb may bedetected capacitively. On the other hand, if the primary local userclient machine is a cell phone, it may not have a mouse or itsequivalent for purpose of determining gripping stress in the hand.However, the cell phone is not without ability to determine user stateby other means such as detecting stress tones in the user's voice,detecting what angle the user is holding the portable device relative togravity, detecting what mechanical stresses the user differentiallyapplies to different parts of the portable device, detecting whether theuser is employing public speaker mode as opposed to private earpiecemode and if in earpiece mode determining how the user is shaking his orher head and/or hand based on change of orientation of the handheldportable device. Knowledge-base rules for processing these varioussituations may be embedded in the user's PEEP record(s) and/or logicallylinked to the PEEP(s).

Beyond the relatively less intrusive biometric detecting devices (e.g.,pulse-detecting wrist watch, wrist band or mouse), some users may bewilling to have their biometric state monitored by more intrusive means.For example, a user may elect to wear special eye glass frames (notshown) that are structured to detect relative head angles and/orrelative eyeball angles and/or relative degree of pupil dilation. Morespecifically, a set of detectors on eye-facing side(s) of the frames maywatch eye movement and pupil dilation and report these wirelessly to theclient machine 115. Integrated motion detectors (e.g., MEMs—miniaturizedelectro mechanical sensors) inside the frame may detect absolute headdirection and/or relative changes of head angles and report thesewirelessly to the client machine 115. Magnetic resonance detectors(e.g., of a functional fMRI kind) or other kinds of electromagneticbrain probing devices may be embedded in the special eye glass frames orin a helmet (not shown) worn by the user so as to detect when certainparts of the brain (e.g., amygdala, orbitofrontal cortex, dorsalstriatum, etc.) become more active or light-up so to speak and therebydiscriminately indicate different emotional or cognitive states (e.g.,fear, doubt, joy, etc.). These brain activity indicating signals mayalso be reported wirelessly to the client machine 115 and processedthereby or relayed to the cloud and processed in the cloud 150.

Referring now more specifically to the first user 111 shown in FIG. 1A;this user may be alone at home 112 in a quiet background environment (asdetected from lack of background noise picked up by a built-inmicrophone (not shown, see 129) of his primary local computer 115) andusing his primary local computer 115 to read the current news on afavorite online newspaper of his (e.g., The New York Times™ Online,where the favoritism for this particular web site is indicated in theuser's CpCC profile of FIG. 1B as will be described below). For purposeof illustration, it is assumed that first user 111 is an adult malehaving a college education or equivalent. One particular item 117 aregarding international news catches the first user's attention. Hereads through it slowly, deliberately; pauses for a while to stare intospace (and to apparently think about what he just read) and then hereturns to focus on the same article and read it a second time. Hiseyeballs (pupils) scan quickly back and forth through the article andpictures during the second read through while he grimaces with his mouth111 c. Video camera 116 (and/or other detectors) pick(s) up all of thesefacial expressions and indicators of locus of focal attention, includedrepeated attention directed to the same content. A video interpretationcomponent in the local client software 105 reports out these video basedindicators as well as the user's point of focal attention 117 a to othermodules of the local client software 105 (or directly to the cloud 150for processing therein). During the reading and re-reading of thefocused-on news article 117 a, the first user 111 may additionallylaunch a search engine (e.g., Google™ News search) and type in certainkeywords that the user 111 apparently associates with the story 117 a.Additionally or alternatively the user 111 may click on varioushyperlinks embedded in the news story 117 a. All of this informationabout user activities associated with the reading of the news article117 a (primary focused-upon content) is relayed into the user's browserhistory 105 c and search history 105 e (or into cloud-maintainedversions of such histories) and is interpreted by the machine means(e.g., by use of knowledge-base rules) as providing additional cluesregarding the user's implied topic or topic domain for the focused oncontent appearing in screen area 117 a. As already mentioned, focal area(e.g., 117 a) and what topic the user is thinking about as he or shefocuses on that content 117 a are not necessarily one and the same. Morespecifically, the news article 117 a may mention a particular person'sname (e.g., a celebrity) and a particular location (e.g., Las Vegas) anda particular time period (e.g., last week). It is generally not possibleto determine from mere identity (e.g., URL and frame ID) of the newsarticle 117 a what topic the user 111 is thinking about. The user may beresearching recent activities of the named celebrity, or recent famousvisitors to the named location (e.g., Las Vegas) or just current eventsof a recent time period (e.g., last week) or a topic that interrelatesall three. The client software 105 accumulates all of these pieces ofevidence or clues and hints as they develop in real time and thesoftware 105 forwards these clues and hints to the match-making service.In response, the match-making service uses one or more topic lookupfunctions thereof (e.g., DLUX services as shall be detailed below) totry and determine from the collected evidence what topics or domains aremost likely the topics/domains that the first user 111 is currentlyinterested in while focusing on this particular news article 117 a. Oneof the clues may be the related keywords which the user entered into hismost recent search engine activity (105 e). In response to the locallycollected evidence, the client software 105 generates one or morecorresponding current focus and current topical interest clues record(118 a—also referred to herein as a CFi or Current Focus identifyingrecord) that identifies the user, identifies the time at which the focalattention was expressed (in Greenwich Mean Time format (GMT)),identifies the focused upon content and optionally provides furtherclues or hints for identifying the probable topic of interest by one ofa variety of means such as by specifying keywords and URL's gatheredfrom recent activity. (See briefly FIG. 2A.) In one embodiment, thetopic of interest or domain of interest may be identified by theuniversal resource locator (URL) of the web page that the user waslooking at during the time of focused attention as well as other URL'srecently looked at. In the same or another embodiment, a firstcollection or snapshot of words found within the area of interest 117 aof the URL identified page is further included in the locally-generatedCFi record 118 a and uploaded to the cloud 150. In one embodiment, theviewed article of interest may included hidden and embedded meta-tags(127 b) which are picked up by the software when the camera 126 detectsthe area of focused attention 127 a of a given user (e.g. 121). Thismeta-tagged information may be further included in the correspondinglygenerated Current Focus identifying record (CFi). Meta-tags (127 b) cancome in a variety of forms including search-engine compatible tags andspecial hierarchy tags (e.g., navMeta-Tags) as shall be described inmore detail below. Each locally generated and time stamped CFi is storedin one embodiment, into a circular buffer (not shown, see briefly FIG.2A instead).

The local client software 105 may sort the collected Current Focusidentifying records (CFi's) according to locally determined intensity ofinterest or emotional involvement scores. Prior to the start of contentscanning by the user (e.g., 111), the user had logged into an onlineinterest matching and compatibility matching service (e.g., 152 of FIG.1B) that is provided by cloud 150 and/or the user's identity wasautomatically determined by face recognition software executing withinhis primary local client machine 115. Depending on available bandwidth,the match making service 152 repeatedly polls the CFi's buffer of theuser's local computer (e.g., 115, 125, etc.) and requests (pulls) copiesof the more recent and optionally more heavily scored ones of the focusand interest identifying records (CFi's) 118 a where the scores and timestamps indicate recent intensity of focal attention and of emotionalinvolvement. (In one embodiment, the action of polling and pulling isdone by selectively dropping or accepting packets from each usermachine, as will be explained shortly.) The pulled CFi records 118 a arerouted to a corresponding Access and Available Resources MonitoringService (AARMS) such as 150 a for parsing of data within each CFi, forlogical linking of data items parsed from successive CFi's (e.g., causeand effect items such content perceived at time point one and emotionalreaction exhibited at later time point number two) and for furtherprocessing of such parsed and logically linked CFi data. Parsed andlogically linked CFi data collections are sent to one or more TopicDomain Look-Up Services (DLUX's) such as 150 b for automaticdetermination of most likely topic areas based on accumulated topicclues and scores given to the clues by the topic lookup service(s). Inone embodiment, topics are split among primary Domain areas (e.g., mostpopular vogue topics relating to sports, entertainment, news,financials, etc.) and more detailed topical nodes that arehierarchically organized under their respective domain headings. One ormore databases may be maintained for tracking users whose current CFi'sindicate a probable interest in one of the topics listed under theDomain or domains monitored by the respective databases. For example,within cloud 150 a first database 151 may be actively keeping track ofnot only the first user's 111 current level of interest in a currenttopic but also keeping track of current interest levels of many otherlogged-in users (e.g., 121, 131, etc.) who are currently focusing onsame or similar content provided by their computers and are presentinghints indicating a same or similar topic of interest on their minds atroughly the same time. The first user 111 may not know this, butsomewhere out on the internet there may be another user (not shown) whois studying the same New York Times webpage (117) and focusing on thesame article area (117 a) at approximately the same time and is alsoindicting; by reading and re-reading the article 117 a, extreme interestin a same topic relating to the focused on material 117 a.

It was noted above that the actions of direct polling of client machinesand of pulling from their buffers is not always possible. For example,when the client machine connects to the internet through one or moreconventional routers (i.e., when multiple computers are on a local LANaccessing the network through a single access point that has a single IPaddress as seen on the internet) there is often no way for a server inthe cloud to uniquely address each of the individual machines behind therouter (and optional firewalls) or to uniquely address each of thebuffers within those machines and determine their states. Instead, inone embodiment, the server can emulate the client CFi's buffer at theserver's end of the communications network and can selectively pollthose emulated buffers and selectively pull from them. Alternatively oradditionally, the server can selectively drop CFi packets sent from theclient as a substitute for the action of not pulling CFi data. Yetalternatively or additionally, the client machine sends buffer statuspackets with upload requests to the server. For example, the clientmachine sends a buffer status and upload packet indicating somethinglike: I have 10 Kb of CFi data for you to upload with the data having anaged data range of 3 seconds to 4 minutes. In response, the server maysend different handshake responses including for example: (1) OK sendall of it to me now; (2) OK send all of it to me during the followingtime slot . . . ; (3) My bandwidth is somewhat limited now, send to meonly your most important 5 Kb or less of CFi data and drop the rest; (4)My bandwidth is somewhat limited now, send to me only your most recent 2minutes worth or less of CFi data and drop the rest; (5) My bandwidth isvery tight now, discard all the CFi data you currently have and do notsend me another request until the following time slot . . . . These aresome examples of how the in-cloud server can control upload data flow.Other communication control mechanisms such as the server sending bufferslack indicators to client machines or sending backpressure messages tothe client machines can also be employed. It is to be understood thatdifferent router and firewall configurations may be used in home and/orbusiness LANs installations and that different specific actions may needto be adaptively taken to emulate various ones of the actions describedherein involving communications between the client machines and thematch-making servers. It is to be understood that even when clients haveunique IP addresses and are uniquely identifiable by the server in thecloud, there may often be hardware or software firewalls preventingdirect access in which case the server may emulate direct access at itsend and use some form of end-to-end automated synchronization of datasets or handshaking in order to effectuate the desired outcome.

The first user's involvement with the given article (117 a) and/or thefirst user's involvement with other associated content that the user 111for example hyperlinked to, or found by way of a search engine search,may be greatly enhanced if the first user 111 was merely informed thatthere are other users out there (e.g., on the internet) like him who arestudying the same article with approximately the same focal intensityand/or approximately the same emotional involvement at the same time. Inother words, the first user is informed that he is not alone in havinginterest of a particular intensity in this particular material and/ortopic at this particular time. In one embodiment, the first user isinformed of how many other users the matching service 152 has identifiedas having a matching focal point of interest (e.g., 117 a) and/or havinga matching interest in a corresponding topic correlated with the focalpoint in a recent time period (e.g., in the last 5 minutes, in the lasthour, last 3 hours, last day, last week, etc.). This information alonecan enhance the user's experience. However, there is more.

The first user's involvement may be even more greatly enhanced if thefirst user 111 could communicate with some of those other, still unknownto him, users about the same or similar topic of interest or even aboutjust the same focused on material 117 a. To this end, the in-cloudmatching service 152 (or more correctly one or more online servers(virtual and/or real) that provide the corresponding services) may pushone or more current chat room invitations (Cciv's) 118 c over a networkand to the local computer 115 of the first user 111. These chat roominvitations may appear as moving icons (e.g., small blinkingsemitransparent dots, larger more solid bubbles, or yet larger animatedtalking heads etc.) flowing on a side banner of the user's screen 117from edge to center or from one end of the banner to the other. In oneembodiment, these chat room invitations appear as blips (e.g., 117 c,117 d of FIG. 1D) on a more prominent radar screen (104) that can forexample pop out from a side border of the user's screen when requestedby the user and then collapsed back to a thin line on the edge when nolonger wanted. When the radar screen (104) is popped out, the user maysee the radar blips displayed thereon as growing in brightness or sizeas they move in from the outer diameter rings towards the center of thesimulated radar scope. The user may also see departing blips asshrinking ones that move outwardly toward the outermost circle, shrinkin size and/or brightness and eventually disappear as they move beyondthe simulated detection horizon of the simulated radar scope. In oneembodiment, the user's local machine outputs unique sound pulses thatsound like sonar blips or metallic clicks through the sound system ofthe local machine when each incoming blip (e.g., 117 c) crosses apredefined radius while approaching the scope's center. This may occureven if the pop-out radar screen is minimized at the time. A blinkingred alert light may also become active on the user's screen for a shortduration even if the pop-out radar screen is minimized. With use, theuser becomes trained to the idea that this unique sound and/or pulsatinglight of a special color indicates an incoming invitation has becomeworthy of attention on his radar scope and that the user may then wantto pop out the scope from his screen side and take a closer look. (Inmost embodiments, the background benign spyware is trained to excludefrom its CFi reports, user responses to the popped out radar screen orto noises emitted on behalf of that radar screen.)

Referring to FIG. 1D; and this example is more so for purpose ofillustration rather than as an indication that the illustrated radarscope 104 is a preferred way of displaying an invitations-indicatingradar scope, the illustrated pop-out radar scope pane 104 may pop outfrom a side banner of user 111's screen when the user clicks on aflashing (blinking) light point at that spot. The pop-out radar scopepane 104 may indicate to user 111 that there is an ongoing first chatroom (represented by an on-screen and dwell-invoked popup balloon 117 b)present on the internet which contains some 90 users already heavilyinvolved in a same particular topic G which user 111 now appears to bethinking about also (this being inferred by the system from the topicclues provided in recent CFI's uploaded from the user's client machine115. The flying airplane icon 117 c shown on scope 104 and associatedwith pop-out balloon 117 b indicates that user 111 is moving his focalpoint on content and his apparent topic of interest into closeralignment with the same attributes of an ongoing online chat representedby invitation 117 b or vise versa. The vise versa is that theparticipants of chat room 117 b are on average moving closer towardscoincidence with the current user's (111) current content of focus andcurrent topic of interest where that topic is categorized under generaltopic area G (e.g., domain G) of the match-making system. In oneembodiment, flying airplane icon 117 c would have caused the user'sclient machine to output an audible alert noise such as a short metallicclick or a sonar echo like blip when icon 117 c was crossing the alertring with value “5”. When the user finally pops out his full radar scope104 in response, he would see that the incoming airplane icon 117 c hasalready advanced more inwardly and is now crossing the co-compatibilityand topic correlation ring with the score value of “10”, this indicatingeven greater convergence between the user's inferred topic of interestand that of the chat room to which icon 117 c invites him. In eithercase, whether user 111 is moving his focus closer to something beingcovered by the chat room of icon 117 c or participants in that room aremoving their discussion closer to something user 111 is focusing on; thefirst user 111 is informed by way of such an on-screen radar scope 104(or the clicking alert sound) that other people (e.g., 50 males, 40females per balloon 117 b and icon 117 c) are currently involved indiscussing roughly the same topic and that user 111 may join that chatroom simply by clicking on the invitation-representing icon 117 c or onits attached explanatory balloon 117 b. In response to user 111 clickingon (e.g., double clicking on, right clicking on, etc. or otherwiseindicating in a machine understandable way that he is entering) icon 117c or balloon 117 b, his computer 115 substantially instantaneously opensa pop out window frame (not shown, but see briefly 316 a of FIG. 3A)containing content from the corresponding online chat. The popped outwindow frame (not shown in FIG. 1D) displays the most recent content ofthe already ongoing chat (or other real time informational exchange),displays the user names of the most recent contributors and indicates toother members of the chat room that user 111 has just entered the chatroom. A live or automated chat room moderator may greet user 111 ornot—depending on how the room is managed—and brief him on what has beengoing on lately in the chat.

With the popped-out chat window frame (not shown in FIG. 1D, see 316 aof FIG. 3A) now available on screen, the first user 111 instantly seeshow other people are currently discussing the topic of probable mutualinterest. Matching service 152 may not always guess correctly as to thespecific topic of interest that drew focus by user 111 to content area117 a. If the automatically produced guess is not on target, no harm isdone because user 111 can quickly close the chat frame and go on withhis business. Such a quick close can be used as feedback by thematch-making system indicating that the system had made a poor match.Alternatively, user 111 may provide explicit feedback to the system byinforming the matching service 152 of his actual topic of interest(e.g., it is not the current poker tournament in Las Vegas but ratherthe Hoover Dam engineer's special interest group called HD.spig) and inresponse the matching service 152 may then alter its behavior (learnedbehavior) accordingly with regard to the meanings of the recent actionsby the given user 111. If the matching service 152 correctly inferredwhat the user's topic of interest is, the first user 111 will usuallykeep the chat room (e.g., 316 a) open for a while. Such a prolonged openstate can be used as feedback by the match-making system indicating thatthe system had made a good match. The user may elect to just observefrom the sidelines the current interactions by other chatterers withinthe opened up room. Alternatively, the first user 111 may elect toparticipate on a more active basis by voting on room content, bycontributing to the room content or conversing (virtually) with otherpeople who are currently in the room and appear to be as heavilyinterested in the same topic 117 a as he is. In one embodiment, even ifthe matching service 152 did not bring the first user 111 to exactly thekind of room he would have preferred to join, the first user 111 isgiven the opportunity to manually browse along adjacent nodes of a topiccategorizing, hierarchy tree full of roughly similar chat rooms (seebriefly FIG. 4B) and find for himself a room more to his liking. Suchtree browsing activity can be used as feedback by the match-makingsystem indicating that the system had made a roughly good match but itcould have done better. The system analyses the results to determine howit could have done better and make small iterative adjustments to itsmatch-making algorithms. Over the course of many users and many suchincremental adjustments, system behavior converges on making betterchoices and bringing users to rooms closer to their liking. Methods forscoring potential chat rooms will be described later below. After havingfound a nearby chat room that seems more to his liking, the user may askthe system to invite him into that room instead. Depending on whetherthat specific room is willing to accept him or not (because rooms canhave their own criteria for acceptability of users) the user is allowedin to that room or a similar but more accepting other room. Thesevarious options for learning of other similarly situated users andopportunities for being invited into like minded chat rooms cansignificantly increase the enjoyment and/or benefit that first user 111derives from his computer and from the internet because now he is almostinstantly (e.g., within a few seconds or less of the match having beenmade and the invitation sent) being joined together with many otherpeople who are engaged in conversation about the very same content offocal attention (117 a, or other content fairly similar to his) and/orabout the same specific topic (or another topic fairly similar to his)or to a general topic domain that he is interested in. He (user 111) isno longer merely studying the material and thinking about the topic allby himself and outside of a social framework. Instead, he is drawn intoa socially interactive circle of like-minded or co-interested people.This can greatly enhance the experience.

Referring to second user 121 of FIG. 1A, unlike the first user 111, sheis of a different gender, a different age, different educationalbackground and a different proclivity for material that interests her.In this example the second user 121 is a female of approximately 16years age and engrossed in an esoteric Celebrity Sensations Magazine 127(fictitious name here) and more specifically in a gossip piece 127 aconcerning a particular celebrity (e.g., Britney). In this particularexample, the topic of interest and the content area of attention focus127 a will be taken as merging into a single entity rather than beingseparate attributes. One reason that such can happen is due to thepresence of embedded meta-tags 127 b in the content where the meta-tagsexplicitly identify the topic of interest as will be explained shortly.Unbeknownst to second user 121, there are two or more like situatedusers 131, 141, etc. active at spaced away locations 130, 140, etc.(location 140 not explicitly shown) who are currently engrossed with thesame gossip piece 127 a, 137 a. No one is yet chatting in a chat roomabout gossip piece 127 a/137 a. However, a matching service 150 c withincloud 150 detects in its database 151 that users 121, 131 and 141 arelogged-in, are simultaneously interested in same content associated witha same topic (e.g., 127 a, 137 a) and that they are indicated to beco-compatible with one another (e.g., by virtue of age, gender,educational background, etc.) for chatting about this point of commoninterest. In this case the cloud 150 automatically spawns an empty chatroom 161 (or temporarily dedicates a preexisting empty one) for use withthe matched content and/or topic (e.g., 127 a, 137 a). The cloud 150automatically sends out invitations (pushed Cciv's 138 c) to theco-compatible users 121, 131, 141 to enter into the empty chat room 161.In one embodiment, chat room 161 includes a use policy dictating thatthere must be at least three (3) active users inside the room (orsimultaneously accepting invitations) if any of the inside or enteringusers has an unvalidated chat profile with respect to the user'sdemographic attributes (e.g., age, gender, location, etc.). The purposeof this policy is to prevent one-on-one chat room situations fromdeveloping where one of the chatters might be a predator and the other avulnerable minor. As long as there are 3 or more participants, noparticipant is left alone with just one other participant and each maybe more wary that improper activity will be reported to the authorities.

Servers within cloud 150 may automatically determine co-compatibilitybetween users 121′, 131′, 141 by comparing their associated profilesincluding Current personality-based Chat Compatibility profiles(CpCCp's) 105 h.1 etc., 105 h′ and so forth (see also FIG. 1B). Withregard to such CpCCp's, the present disclosure generally refers to thesame as “personality” based profiles because that is the more frequentand more easily understood use of the such CpCC profiles. They can beused to cluster together in chat rooms, or elsewhere, users who arepersonality-wise co-compatible with one another. However, there areinstances in the present disclosure where the same CpCC profiles aremore broadly referred to as “personhood” based profiles, because forexample, only the demographic or credentials sections of the profilesare used and the latter do not necessarily reflect the personality-basedlikes and dislikes of the user. Accordingly, the term “personhood” basedprofile is to be understood as being broader and to encompassdemographic and/or credential attributes of the user as well asgenerally encompassing personality attributes. In one embodiment,machine-stored co-compatibility distance scores are developed as betweenusers (see also FIG. 5A). The compared profiles that are used forgenerating such co-compatibility distance scores may include not onlythe CpCCp's but also Domain-specific Chat Compatibility profiles(DsCCp's)—just one shown at 106 h′ in FIG. 1A but see also FIG. 1C.These CpCCp's and/or DsCCp's may be first partially formulated in therespective local computers of the users and then uploaded into the cloud150 for use in making matches and developing community-approvedreputations. Alternatively or additionally, the CpCCp's and/or DsCCp'smay be preformulated as stereotyping templates and stored in the cloud.In one embodiment, template profiles that fit stereotypical personswithin the system's user population are made available, applied to newusers who are joining the system and then minor modifications are madeto the applied stereotyping template profiles so that they become morerepresentative of the associated individual user to whom they areapplied. Such an approach can lighten the workload for each new user whowishes to have an individualized profile created for him or her and itcan also allow users who do not have individualized profiles to enterand use the system under the guise of the template profiles (e.g., asanonymous guests who are giving the system a test drive).

Before discussing in detail data structures of profile records such asCpCCp's 105 h-etc. (see FIG. 1B) and such as DsCCp's (e.g., 106 h.1, seeFIG. 1C), a few additional features of system 100 are to be noted here.Some users do not enjoy fighting for attention in crowded, heavilypopulated chat rooms (e.g., more than 10 active participants at onetime). They may express a preference for smaller chat rooms or roomswhere the population is maintained in range that is comfortable for itsusers. Alternatively or additionally, some participants in asystem-formed chat room (e.g., 162) may find other participants to bedisagreeable to them even though their CpCCp's 105 h-etc. were initiallydetermined to be co-compatible and thus matched by the system cloud 150.In the latter case, users may express their displeasure throughconscious (explicit) or subconscious (implicit) negative votes expressedin corresponding Current voting indicators (e.g., Cvi's 138 b). In oneembodiment, right clicking of a mouse while the mouse-controlled cursoris over an item of focus opens up a pop out menu (see 336 of FIG. 3A)that includes vote indicating buttons and interest indicating buttons.The user left clicks on one of these items to register an explicit voteor an explicit indication of interest. Current voting indicators (Cvi's)may be implicitly generated by biometric indicators in the same way thatCurrent focus identifying records (CFi's) are generated except thatimplicit Cvi's are generated while the user is engaged inside a chatroom frame (e.g., 316 a of FIG. 3A) while implicit CFi's are generatedwhen the user is engaged inside a nonn-chat, content-containing frame(e.g., 317 of FIG. 3A).

If a first set of one or more users express persistent displeasure witha second set of users within a given chat room (e.g., 162 of FIG. 1A)through their respective negatively-directed Current voting indicators(e.g., Cvi's 138 b), the cloud 150 may automatically detect this andresponsively cleave the room (e.g., 162) automatically into two childrooms (e.g., room 162 a containing 7 participants and room 162 bcontaining 3 participants). Participants in each child room may be toldthat the cleaved off other participants have “left the room”, if theyare told that at all. In one embodiment, a juveniles containing room isnever cleaved to have less than 3 or 4 participants in it depending onsystem policy for chat rooms containing non-adult participants.

Just as some users may prefer small rooms (e.g., 5 or lessparticipants), others may prefer larger rooms. The cloud 150automatically detects this from the CpCCp's or other profiles of theusers. If two rooms each have too few of a number of participants inview of the user desires expressed in their profiles, the systemautomatically detects this and automatically fuses (combines) two smallparent rooms (e.g., say room 162 b containing 3 participants and room163 containing 2 participants) into one larger room 164 of co-compatibleand larger-crowd seeking participants. Preferences are determined basedon user Current Chat Compatibility profiles directed to personality andtopic (CpCCp's and DsCCp's) which are stored in database 151 and whosedata structures are now detailed with reference to examples, first inFIG. 1B and then in 1C.

Referring to FIG. 1B, in one embodiment 102, the cloud 150′ includes aplurality of compatibility profile storing servers 152. A given user121″ may have a plurality of compatibility profiles such as 105 h.1, 105h.2, and 105 h.3 assigned to him or her. This is so because profile datamay change with change of user mood and/or change of other factors. Onlyone of the personality-based compatibility profiles or CpCCp's will bedeemed as the ‘current’ personality-based chat compatibility profile forthe moment based on an explicitly stated or implicitly determined moodand/or surroundings of the user 121″. (The dashed, arrow-headed linesextending from near user 121″ to alternate profiles 105 h.2 and 105 h.3indicate that designation of one of them as the current profile canchange in response to machine-implemented detection of changedcircumstances, such as a mood change by the user and/or a change ofsurroundings and/or a change of topic and/or a change of time forexample from a business day to a weekend or holiday.) The mood of theuser may be explicitly indicated by the user or implicitly obtained fromrecently pulled Current focus indicators (CFi's) 128 a′ and/or fromcurrent voting indicators and/or from local surroundings (such asindicated by GPS 111 z or nearby RFID tags). Mood, surroundings and/orother user attributes may affect the preferences defined in thepreference columns 158 (likes and dislikes) of the personality-basedcompatibility profile. The second column 154 labeled as “mine” remainsrelatively constant irrespective of the user's changing moods. Morespecifically, when user 121″ is in a first mood, she may prefer to chatwith chat buddies who generally agree with her current position (e.g.singing to the choir so to speak) regarding a Domain-nonspecific topic.Contrastingly, on a different day or in a different environment, user121″ may be in a different mood (e.g. corresponding to profile 105 h.2)where she desires to debate with people who hold views diametricallyopposite to her own. As mentioned, the user 121″ may indicate hercurrent mood to the system either explicitly by pressing appropriatechat control buttons (e.g. right mouse click) or implicitly throughcurrent votes and/or current focus and topic-of-interest indicators.Surrounding environment may be detected through a GPS module 111 zand/or through peripheral cues picked up by camera 126 and/or othercameras and/or through background sounds picked up by the one or moremicrophones (129) and streamed to the cloud for analysis.

The currently-in-effect personality-based chat compatibility profile(CpCCp) (i.e., having mood or surrounding related to identificationnumber 105 h.1) may be viewed as having a plurality of horizontalregions, e.g., those designated as demographics rows 171, reputationrows 172 and credentials rows 173. Additionally, as seen in FIG. 1B, theexemplary CpCCp 105 h.1 may be viewed as having at least 4 vertical dataholding columns, a first of which is designated here as “mine” (154), asecond of which is designated here as representing positive scoringcriteria that define desirable chat buddies (155), a third of which isdesignated here as representing negative scoring criteria that defineundesirable chat buddies (156), and a fourth of which is designated hereas representing averaged or mean criteria for desired chat roomproperties (157). Additionally, as seen in FIG. 1B, the exemplary CpCCp105 h.1 may be viewed as having a mood-and-personality directed set ofknowledge-base rules 175 that provide for finer determination of userpreferences based IF/THEN declarations and variables inside the IF/THENexpressions. Criteria items in each of the 4 vertical columns 154-157and/or in the knowledge-base rules set 175 may be stored as parametername and value pairs in a relational database or another appropriatestorage structure. For example a username may be designated as “Name:=”and then this parameter name setting may be followed by the value datarepresenting the username. Similar parameter name and value pairstructures may be used for the other indicated values in FIG. 1B. In oneembodiment, an industry recognized and so-called JSON notation protocol(JavaScript Object Notation) is used. However, to avoid illustrativeclutter these various details are not shown in FIG. 1B. It is to beappreciated that the CpCCp's of FIG. 1B are to some extent, independentof the hierarchy tree of domains and topics shown in FIG. 4B. Thegeneral demographics 158 of desired or undesired chat buddies can bespecified independently of a specific topic or a specific topic domain.Combinations of personality based preferences and topic related changesin preferences may be specified in the knowledge-base rules set 175.(For example, one rule might read as: IF Room_Topic=A ANDRoom_member=MBGFFL THEN increase co-compatibility score by +10.) It willbe seen in FIG. 1C that topic dependent preferences 187 (DsCCp's) mayalso be specified with respect to specific topics of interest. Oneexception to the above general rule for FIG. 1B is that users mayspecify favorite topics (see the box labeled as 154-7 a) as well asfavorite books, favorite movies, etc, as constituting part of thedescription of their personalities and/or parts of description ofpersonalities of chat buddies they may like or dislike. In oneembodiment, users may also specify most disliked topics, movies, books,URL's, etc. as well as favorites.

The demographic data of the local user 121″ is stored in a databaseregion represented in FIG. 1B by the first horizontal region 171 (whichmay have plural rows) and the first vertical column 154 labeled “mine”(which in some cases may have plural subcolumns). In this particularexample, user 121″ has indicated her age to be between 16 and 17 yearsold and her gender to be female and her socioeconomic class to be middleclass. She has also indicated her geography of permanent residence andtime zone to be the central time zone of the USA. She has designated herpreferred language as American English (as opposed to British Englishfor example). When user 121″ first provides this information it istagged as being ‘unvalidated’. This is so because no trusted other user(or trusted system program) has validated the alleged age, name, genderetc. of this user. However over time and through usage, votes by trustedother users in the system may be used to switch one or more of theselocal user-provided demographic data items (mine) to be tagged asvalidated data, meaning that others have validated her alleged age, heralleged gender, and so forth. Some users may demand to deal only withother users whose demographic data (or a prespecified portion thereof)has been validated. Others may not care. These preferences may bespecified in each user's likes and dislikes columns (e.g., in column155, user 121″ specifies that she prefers the alleged gender of her chatbuddies to be validated as female and she also prefers that theiralleged ages be validated as being in the range 15 to 18 years old. Inone embodiment, users may also specify levels of importance or weightsto be used by the match-making system when scoring these variouspreferences to find co-compatible other users or co-compatible chatrooms. For example, some preferences may be designated by the user asbeing more like “must haves” while others may be designated by the usersupplied weights as being closer on the spectrum to “don't really care”if this preference (or dislike) is adhered to, it is just a fineresolution adjustment as opposed to a coarse adjustment regardingpreferences.

Referring to vertical column 155 (desirable chat buddies), user 121″ hasindicated that the chat rooms she would like to be invited intopreferably should include another user whose username happens to beMBGFFL (which may stand for My Best Girl Friend For Life). The preferredinclusion list could have plural usernames in it. User 121″ has alsoindicated that the stated demographic age groups for desired people inthe ideal chat room should be in the range of 15 to 18 years old andthat these should be validated age indicators. Additionally, she hasrequested that most of the chatters be of the female gender (this beingreinforced in column 157) and that this gender designation be avalidated one. When a co-compatibility finding server (one containingdatabase 151 of FIG. 1A) searches for users who are to be grouped (e.g.invited) into a same chat room, it uses the data in column 155 (desiredbuddies), not as mandatory requirements, but rather as aco-compatibility positive score creating sets of points-generatinginformation. Positive points are added for every matched criterion.These may be differently weighted.

As mentioned above in some embodiments the users can provide suggestedweights to be applied to the various stated preferences or stateddislikes. However, a user's actual behavior may show subconsciouspreferences (or dislikes) that are quite different from the stated onesand/or weighted differently than the user-state weights. In oneembodiment, the cloud 150 includes trend detecting services that run inthe background and analyze each user's actual behavior (e.g., which chatrooms she or he actually joins and engages in forcefully). The trenddetecting services (see for example 437 of FIG. 4A) determine the moreaccurate weights to be applied to the stated and actual preferenceattributes of the user. In one embodiment, each user may view thechanges made by the trend detecting and adapting services to that user'sprofiles and that user may reverse or halt such automated changes to atleast some of the entries and/or their weights in the profiles.

When the match-making services score the weighted (or unweighted)preferences positively and the weighted (or unweighted) dislikesnegatively and add these scores together (or apply them to a morecomplex function for determining co-compatibility, the resultingco-compatibility score signals (could be along different dimensions suchas one for topic co-compatibility and another for personalityco-compatibility) tends to increase as more of the desired chat buddyproperties are met and decrease as more of chat buddy dislikes (column156) are met. A relatively high co-compatibility score indicates agreater likelihood that user 121″ will find the other chat buddies inthe proposed chat group to be co-compatible with her desires at thecurrent moment. Near the end of the process (detailed more below),different co-compatibility scores based on personality will have beendeveloped for a given user i.e., 121″ and the proposed groups of otherusers (e.g., 131′, 141′ of FIG. 1A) with which she is to be joined in anempty room (e.g., 161) and/or for a given user i.e., 121″ and theproposed already populated chat rooms into which she may be invited.Some proposed but-not-yet formed groups (e.g., 121′, 131′, 141′ of FIG.1A near room 161) may score high while other proposed but-not-yet formedgroups (not shown) may score lower. Some proposed and already populatedchat rooms (e.g., 162) into which user 121″ has not-yet-been invitedinto may score high while other proposed and already populated chatrooms (e.g., 163) may score lower. The match-making system sorts thescored rooms or other users and then picks the higher ones or thoseexceeding a predefined threshold. Then the system sends invitations tothe given user i.e., 121″ only for the picked higher scoring chatopportunities. All this happens automatically in the background and thususer 121″ is not bothered with considering the merits of chat rooms orchat groups that scored poorly and to which chat opportunities she wasnot invited. Instead, user 121″ is presented with invitations to themore highly scoring opportunities (these invitations may come in theform of in-flying radar blips like 117 c, 117 d of FIG. 1D) and she getsto choose, if she wants to bother to at the moment, from among thehighest scoring ones and thus the ones most likely to have chat buddieswho are co-compatible with her preferences (e.g., the personality anddemographic based ones expressed in her CpCCp 105 h.1).

Since various permutations of not-yet-joined users and rooms may bepossible, in one embodiment co-compatibility distance graphs are formedand represented by stored digital data. FIG. 5A shows an example whileFIG. 5B illustrates one possible process for using the representedgraphs. Referring to FIG. 5A, first user 121 (call her Sally) has acorresponding set of one or more profiles (e.g., 505 a, 506 a) whichrepresent her preferences for meeting up with other potential users, forexample with second user 111 (call him Sam here). Sam has acorresponding set of one or more profiles (e.g., 505 b, 506 b) whichamong other things represent his demographic attributes (see 154 “mine”of FIG. 1B). The system automatically generates a weighted score(Score₁₂) that represents how well Sam's demographic attributescorrelate with Sally's preferences. The reciprocal (1/Score₁₂) of this,if positive and finite, may be taken to represent a distance vector 512that originates with Sally's preferences (e.g., 505 a, 506 a), extendsto Sam's demographic attributes, and is referred to here as theSally-to-Sam distance. (Of course user-to-user distance values may begenerated with functions other than the score reciprocal and stillprovide roughly similar results. Accordingly any function where distanceshrinks in response to the co-compatibility score going up (e.g.,Distance=Large_Number minus Score) may be used as deemed appropriate bysystem administrators to provide a desired kind of clustering. Forexample, distance might be computed as D=1/(Score squared) or asD=Q(score)/P(score) where P and Q are polynomials. Additionally, thescore used in these functions might be logarithmically or otherwisetransformed.) If the Sally-to-Sam score (Score₁₂) is zero (or asub-threshold number close to zero), then distance goes to infinity andno linking vector 512 is created at all. Similarly, if the Sally-to-Samscore (Score₁₂) is negative, then it is taken to mean that Sallystrongly objects to meeting up with Sam, and as a result, no linkingvector 512 is created at all. On the other hand, if the Sally-to-Samscore (Score₁₂) is a relatively large positive number, then theSally-to-Sam distance vector 512 exists and it is relatively short. Thismay be taken to mean (depending on how long or short the computed vector512 is) that Sally 121 is willing to entertain the possibility ofmeeting up with Sam 111 in a chat room (say 561 for example).

While first vector 512 is drawn from Sally-to-Sam with a respectivefirst distance (in a one or two dimensional co-compatibility space or ina space of 3 or more dimensions, where each dimension is a differentkind of co-compatibility factor), a different second vector 521 is drawnfrom Sam-to-Sally based on a system generated, weighted score (Score₂₁)that represents how well Sally's demographic attributes correlate withSam's preferences. In this case, Sam is shown in phantom at location111* and a dashed distance vector 521 is shown to represent thecorresponding counter distance. The reciprocal (1/Score₂₁) of theSam-to-Sally score, if positive and finite, may be taken to representdistance vector 521 that originates with Sam's preferences (e.g., 505 b,506 b), extends to Sally's demographic attributes, and is referred tohere as the Sam-to-Sally distance. (Of course user-to-user distancevalues may be generated with functions other than the score reciprocaland still provide roughly similar results.) If the Sam-to-Sally score(Score₂₁) is zero or almost zero, then distance goes to infinity (beyonda predefined maximum) and no linking vector 521 is created at all.Similarly, if the Sam-to-Sally score (Score₂₁) is negative, then it istaken that Sam strongly objects to meeting up with Sally, and as aresult, no counter-linking vector 521 is created at all. On the otherhand, if the Sam-to-Sally score (Score₂₁) is a relatively small positivenumber, then the Sally-to-Sam distance vector 521 exists but it isrelatively longer (longer than first vector 512 in the illustratedcase). This may be taken to mean (given the relatively large distancedefined by vector 521) that Sam 111 is less willing to talk with Sally121 than the vise versa condition concerning Sally's willingness to meetup with Sam 111 in a chat room (based on their respective profiles).

In this example (FIG. 5A) it will turn out that Sally and Sam will notbe invited to join together in a system spawned empty room (e.g., 561)due to the comparatively long distances, 512 and 521, found between themand contrasted to shorter distances like 513 and 514 found between Sallyand other users Sharon (131) and Sandra (141). In one embodiment, thefollowing additional steps are taken. If, as between Sally and Sam,there are two distance vectors, 512 and 521 of different lengths, thelarger of the distances (521 in this case) is taken as a linking pathdistance between Sally and Sam. On the other hand, if as between Sallyand Sam, there is only one distance vector because the score of thecounter vector was not greater than or sufficiently greater than zero(>>0), then no linking path and linking path distance (each of which isrepresented by system stored data) is created. The not-created linkingpath and linking path distance is not considered in later algorithms,which for example, sort users according to the linking path distancesbetween them (see 527 of FIG. 5B).

Next, as seen In the example of FIG. 5A, counter vector pairs 513/531and 514/541 are respectively defined (by machine stored data) betweenSally 121 and Sharon (131) and Sandra (141) respectively. Linking pathsand linking path distances (not explicitly shown) are defined (by systemstored data) for each of the counter vector pairs 513/531 and 514/541.An empty and floating chat room 561 is spawned by the system and firsthypothetically linked, as part of a trial and error process, to Sally121 by way of counter vector pair 515/551. The empty room 561 has itsown set of profiles (e.g., CpCCp 505 e and DsCCp 506 e). While onlySally is linked to room 561, the room's profiles (e.g., 505 e and 506 e)are mirror copies of Sally's profiles (e.g., 505 a and 506 a). Thetemporary linking distance between floating room 561 and Sally will bezero (not shown). However, in a next part of the trial and errorprocess, Sharon 131 will be hypothetically linked to room 561 and thatroom's profiles (e.g., CpCCp 505 e and DsCCp 506 e) will beautomatically readjusted to pretend that both Sally and Sharon haveentered the room. (They have not yet even been invited into the roomthough. This is still part of the trial and error clustering process.)Since Sally 121 and Sharon 131 have different profiles, the linkingdistance (the longer of vectors 515 and 551) between Sally 121 and thefloating empty room 561 will be nonzero. Another nonzero linkingdistance will also form between Sharon 131 and the floating empty room561. For sake of avoiding illustrative clutter this other link is notshown.

Next, as part of the trial and error clustering process, Sandra 141 ishypothetically linked to room 561 and that room's profiles (e.g., CpCCp505 e and DsCCp 506 e) will be automatically readjusted again to pretendthat all three of Sally, Sharon and Sandra have entered the room.Accordingly it is seen that user-to-room linking distances change asmore users are hypothetically added to the room and also that the room'saveraged (or otherwise formed) variable profiles (e.g., CpCCp 505 e andDsCCp 506 e) will change in response to trial and error addition of eachfurther user. At some point, user-to-room linking distances may exceedone or more predefined limits and the trial and error process will bestepped back to return to acceptable distances and possibly halted atthat time.

So one possibility is that free agent users (floating users) like 121,131 and 141 have no pre-established room to join into and the systemspawns an empty room (e.g., 561) for them and starts determining throughtrial and error how to populate the room with closely clustered users(closely clustered in the graph space) such as 121, 131 and 141. On theother hand, in the case of Sam 111, the system may find an alreadypopulated chat room B (563) where the linking distance (526/562) fromSam to the room (B) is within predefined limits. In that case, Sam willbe invited to enter populated room 563, and if he accepts theinvitation, the profiles of room 563 will be adjusted accordingly toreflect Sam as a new member.

Referring to FIG. 5B, a corresponding machine-implemented process isillustrated by way of flow chart. Entering into step 520, a data centerservice such as an AARMS (411) provides the CFi's or other clusteringsupport data (via input 520 a) for a plurality of “floating” users. Byfloating users, it is meant here that these users of client machinesappear to be in need of being matched to corresponding chat rooms. Theneed for matching may be due to the fact that these users are notcurrently engaged in a chat room and their client machines are uploadingfresh new Current focus identifying records (CFi's) or for other reasonsas the system may deem appropriate. In step 520 the floating users(e.g., 111, 121, 131, 141) are segregated into groups according tosameness and/or similarity of the focused upon content that has beenidentified by their respective CFi's. In one embodiment, suchsegregation is based only exact sameness of the focused upon content(e.g., same exact URL). In other embodiments the degree of similaritybetween different URL's or other content is determined by the AARMSservice module (e.g., 411) before it hands over a match-making job toone of its DLUX modules (e.g., 415) and the scope of similarity ornonsimilarity tolerated may vary from data center to data center orAARMS to AARMS. For example, in one data center, a specific AARMS may beconfigured to automatically determine that first users whose URLincludes the string, “soccer” and second users whose URL includes bothof the strings, “football” and “UK” are in fact focusing on same orsimilar content (although the respective topic of interest for theseusers has not yet been determined and optionally will be in optionalstep 522). In one embodiment, database records and/or knowledge baserules are empirically developed and kept for identifying differingcontent sets that are nonetheless to be deemed as being substantiallysimilar, focused upon content.

After users are segregated into respective groups based on samenessand/or substantial similarity of focused upon content in step 520, eachgroup is respectively further processed in step 524. It is to beunderstood with regard to the illustration in FIG. 5B of sequentialsteps that each group or subgroup or user may be processed by paralleldata processing means as well as by serial von Neuman machines where thelatter is used in one embodiment. In one embodiment, between the handingoff of each same/similar-content group from step 520 to 524, the groupmay be first handed off to a corresponding DLUX (e.g., 415) where instep 522 the DLUX generates topic sameness probabilities (or scores) foreach group member based on their recent CFi's (e.g., 75% chance user isthinking about a USA soccer team, 30% chance it's a British soccer team,etc.).

In step 524, the same/similar-content group is further segregated intosubgroups of floating users according to sameness and/or similarity ofthe domain and/or topic that is probably on their minds. For example,one subgroup is formed of users who have similar probabilities that theyare thinking about a USA soccer team in conjunction with thesame/similar-content that has been identified by their CFi's, while asecond subgroup is formed of users who have similar probabilities thatthey are thinking about watching an upcoming USA versus UK soccer (or“football”) game on TV this weekend. The number of subgroups that areformed depends on system resource availabilities. If the currentworkload is heavy and resources are strained, each subgroup maycorrespond to a low resolution domain. On the other hand, if morebandwidth is available, each formed subgroup may correspond to a higherresolution subtopic residing under a topic node which resides under acorresponding domain node (see FIG. 4B).

In an alternate embodiment (not shown), module 522 appears before module520 and module 522 of this alternate embodiment provides scores for say,the three most likely domains (pre-established domains in the systemhierarchy tree) each user is probably thinking about. These scores areused to define clustering distance vectors similar to those of FIG. 5Abut only in a topic closeness space that does not take into accountpersonality-based, chat co-compatibility or sameness and/or substantialsimilarity of the focused upon content of the different users. So it isa crude first step way of first clustering users around nodes of thesystem hierarchy tree without testing a priori for personality-based,chat co-compatibility or sameness and/or substantial similarity of thefocused upon content. It is to be appreciated from this that the presentdisclosure contemplates various permutations besides those illustratedin the drawings. So in contrast to FIG. 5A where the distance scores maytake into account all the user's preferences (as defined in theirpersonal profiles) and/or the room preferences (e.g., as defined byaveraged room preferences), users may be step-wise incrementally movecloser to their ultimate clusters by first clustering accordingdistances of each user from pre-established domain or topic nodes in thesystem hierarchy tree and then secondly revising the distancing mapsaccording to sameness and/or substantial similarity of the focused uponcontent of the different users or according to personality-based, chatco-compatibility. In one embodiment, sameness and/or substantialsimilarity of the focused upon content is not determined and onlycloseness based on topic scores is used to cluster floating users closerto or further away from each other. In yet another embodiment, users arefirst clustered closer or further away from another based onlypersonality-based, chat co-compatibility; and then only after that arethe distances refined based for example on sameness and/or substantialsimilarity of the focused upon content of the different users (oralternatively, based on the scored distance of the users relative topre-established domain or topic nodes in the system hierarchy tree).

While it was mentioned above that topic-based distance scoring may bevaried as a function of cloud workloads, it is also within contemplationof the present disclosure that topic-based distance scoring be varied asa function of CFi hint specificity and richness. More specifically, someuploaded CFi data sets may contain a rich set of topic hints thatclearly point to a specific topic node within the system hierarchy tree.Accordingly, the user associated with this rich CFi set may be finelypositioned among set of highly specific topic nodes and his finely-tunedscore used to determine which of the highly specific topic nodes are theones that most likely reflect what is on the user's mind. By contrast,the uploaded CFi data set of another user may contain only hints thatare very vague as to what specific topic that user has on his or hermind. In the latter case, the user will be crudely positioned in topicnode space next to a major domain or to a low resolution topic node butnot next to a highly specific topic node. Accordingly, users whoseuploaded CFi data sets contain only vague hints as to probable topic onthat user's mind are float-wise positioned in topic node space next to amajor domain (including the generic catch-all domain) or to a lowresolution topic node (including a generic catch-all topic under aspecific system domain) and such users therefore cluster close to oneanother. In one embodiment, the topic node space is defined as a polarcoordinate space (see FIG. 6) with the generic catch-all domain (D0 ofFIG. 6) being positioned at the origin, the system domains (D1, D2, . .. Dn) being positioned at close radial distances (but different polarangles, e.g., at R=1) around the origin and highly specific topic nodes(e.g., T1.1, T1.2, etc.) and subtopic nodes (e.g., ST1.1) beingpositioned progressively further away from the origin (e.g., R=10, R=100plotted logarithmically). The far-away from origin positioning of thehighly specific topic nodes (e.g., ST1.11) prevents vague CFi providingusers from being accidentally clustered near to these highly specifictopic nodes and keeps those users relatively close to the origin (e.g.,closer to D0 than to ST1.1). In one embodiment, if a single, rich CFihints providing user (e.g., outer orbit Larry 651 of FIG. 6) ends upbeing clustered all by him or herself in the outer reaches of this polarspace (e.g., at R=1000, radius circle not shown) because no other useris currently providing such rich, highly specific CFi upload hints data,the radial positioning of the lone user (e.g., 651) is automaticallyscaled back to thereby reposition him or her closer to the origin andthus closer to where other users (e.g., 611, 621) are more likely to be.The polar angle(s) (in N-dimension polar space, where N=2, 3, etc.) ofthe scaled back user remains the same so that he thereby remains withinthe shadow angle of his encompassing domain(s) or topic(s) (see forexample the illustrated shadow angle 602 of topic T1.1 and shadow angle601 of encompassing domain D1).

A few more words are in order here regarding FIG. 6. The actual domainor topic node does not necessarily consume area or an arc segment in thetopic space 600 of FIG. 6. Instead each node can be a point node of nowidth or height, and whose position is illustrated as a crosshair inFIG. 6. Thus there can be an almost infinite number of domains on radiuscircle (R=1), but not quite infinite because polar space 600 is definedin a finite machine memory. Each domain node (e.g., D6) can cast acorresponding one or more shadow angles (e.g., 603) that are associatedwith it where each such shadow angle may have a vertex at the origin andits start of shadow casting begins at the radius of the node and extendsout toward infinite radius. Shadow angles of same radius domain or topicnodes can overlap with one another in one embodiment. Their cast areasdo not have to be mutually exclusive. The catch-all domain D0, of coursedoes not need a shadow because it covers essentially all angles of thetopic space 600 (there can be forbidden zones). While domains D1, D2, .. . , Dn are shown to be ordered in a particular sequence around the R=1radius, it is to be understood that this is a nonlimiting example in atwo dimensional illustrated polar space 600. It is within thecontemplation of the disclosure to organize domains in 3-D or higherdimensioned polar space (e.g., with complex number planes) withdifferent shadow angles for different angular dimensions. It is withinthe contemplation of the disclosure to define multiple organizations ofdomain and topic nodes relative to one another in different ones ofselectable spaces.

By way of a more specific example of the use of the illustrated 2-Dpolar space 600, it is assumed that recent uploaded CFi hints belongingto Sam (611) position him close to topic node T1.2. Recent uploaded CFihints belonging to Sally (621) position her midway between domain nodeD1 and topic node T1.2. Recent uploaded CFi hints belonging to Larry(651) position him at an angle of sub-topic ST1.45 but much further outin this solar system of domain and topic nodes, say at R=1000. SinceLarry 651 is alone in the current overlaying of his determined topic ofinterest on polar space 600, a first automated step scales Larry'sposition radially back, but at his original angle, to say R=100 and atest is conducted to see if other users are nearby. If no, a nextautomated step scales Larry's position radially back, but at hisoriginal angle, to say R=10. Once again it is tested to see if Larry isall alone. This time the answer is no because Sam 611 is nearby.Ultimately Larry and Sam may be invited to join a chat room (not shown)running under the auspices of topic node T1.2. Sally 621 may be invitedto join the same chat room. However automated determinations as to whichroom if any each user will be invited to join may be made on the basisof computed distances (e.g., 622-624) in topic space 600 between eachuser and nearby topic nodes and/or computed distances (e.g., 625) intopic space 600 between nearby users. In one embodiment, users who aremuch closer to each other (in other words, they are closely clustered)in topic space 600 than to nearby topic nodes are automatically invitedinto a newly spawned room that is automatically spawned for them becausethey are so closely clustered (e.g., within a predefined distance),topic wise to each other. Of course invitations may be predicated insome embodiments on personality co-compatibility and/or other attributesbesides that of closeness within the topic space 600.

It was mentioned above that recent uploaded CFi hints belonging to Sally(621) position her midway between domain node D1 and topic node T1.2.Here is how the same is machine implemented in one embodiment. Actuallyand initially, a DLUX analysis of the recent uploaded CFi hintsbelonging to Sally (621) provide a first relatively high scoreassociating her recently uploaded CFi hints with domain node D1 and asecond relatively high and roughly the same score associating herrecently uploaded CFi hints with topic node T1.2. The DLUX analysis mayprovide yet other scores that place her near, say domain node D6 (wheresuch placement is not shown in FIG. 6). In a next machine-implementedstep, DLUX placement that are relatively close to each other (e.g.,within a system predefined distance and/or within a system predefinedangle sweep) are consolidated into a single placement point by weightedsumming (e.g., averaging) of the original positions in topic space 600,where the weights are functions of the original DLUX scores. SinceSally's scores for node D1 and node T1.2 are roughly the same, she endsup through averaging to be placed approximately midway between the twonodes. In the same example, initial DLUX analysis of the recent uploadedCFi hints belonging to Sam (611) generated roughly equal scores placinghim simultaneously along the R=10 circle at topic node T1.1, T1.2, . . ., T1.4 (last one not shown even though its associated ST1.45 is). Asomewhat lower DLUX generated score simultaneously placed Sam at domainnode D1. Machine-implemented weighted averaging of all these closelyspaced positions caused Sam to become placed just inside of the R=10circle near topic node T1.2 (as shown within the shadow angle 601 ofdomain node D1). It is to be understood that these weighted averageplacements of Sam, Sally and Larry in the topic space 600 are based onrecently uploaded CFi hints belonging to respective users. It is withinthe contemplation of the disclosure to additionally and automaticallygenerate trending data that shows progression of respective users overtime in different topic sectors (e.g., one sector being in the shadow601 of D1 for example and another being in say, the shadow 603 of D6)and shows regions of the topic space 600 where the respective users tendto focus on. The history window of such trending data may vary fromuser-to-user given that some users may exhibit wildly volatilemigrations from one topic to another whereas some users may exhibithighly consistent and stable concentration in certain areas of topicspace 600. A background service of the match-making andinvitations-generating system (MM-IGS) scans through the topic spacetrending data of the different users and determines what size of historywindow is appropriate for each. The adaptively variable history windowsize is stored in the user's account settings (432 of FIG. 4A) or in thetrending data store (437).

Returning back to the example of FIG. 5B wherein users are firstclustered according to sameness or substantial similarity of theirfocused upon content; in step 527, for each subgroup formed by step 524,the system computes the linking distances (if any exist, and in acombined scores space for content and topic sameness) between each ofthe users of that subgroup. At this stage each user in the subgroup isalready known to be focusing on same or similar content (because of theinitial segregation that took place in step 520) and is believed to bethinking about a same or similar topic (because of the refiningsegregation that took place in step 524). The computed linking distancesindicate the likely co-compatibility between the users based on thecombination of content and likely topic. Closer ones are more likely tobe co-compatible in combined topic and content space. As mentionedabove, co-compatibility can be further determined (refined) on the basisof Current personality-based Chat Compatibility profiles (CpCCp's).Topic co-compatibility can be further refined on the basis of detailedinformation provided in the current Domain specific Chat Compatibilityprofiles (DsCCp's) of the users. In one embodiment, if a user does nothave a CpCCp, the system automatically fetches a default stereotypingprofile for the user from a default profiles storage region (e.g., 510of FIG. 5A). The specific default profile(s) to be fetched may depend onthe navigation paths the user took to get into theinvitations-generating system (e.g., she entered via a link provided onthe home page of Celebrity Sensations Magazine (a fictitious companyhere)). In one embodiment, after the system automatically assigns one ormore default profiles to a user, the user may optionally view theprofile and make changes (deltas) as is indicated by bubble 511 of FIG.5A. In cases where the deltas are small and few, the system may store anidentification of the default profile and store only the small deltasfor the user in the user's account (e.g., 432) rather than storing aseparate full profile. Although FIG. 5A shows at 510, a CpCCp defaulttemplate bundled with a DsCCp default template, such an arrangement isnot necessary or always the case. The CpCCp default template isautomatically assigned based on assumed personality and demographicattributes of a new user (for example due to a detected Web browsingnavigation path she took just prior to engaging with theinvitations-generating system). On the other hand, one or more DsCCpdefault templates may be independently and automatically assigned to thesame user based on a detected search engine usage she performed shortlybefore engaging with the invitations-generating system. In oneembodiment, all users are initially assigned a default CpCCp templateand a default root DsCCp template even if they had not responded to aninitial user questionnaire supplied by the system. If they have notresponded, the assigned default templates are very generic. If they haveresponded, the assigned default templates are more specific, withspecificity being function of how deep down into the questionnaire theuser went before quitting. In one embodiment, the first page of thequestionnaire simply asks for age, gender and geographic location. Theuser may quit and not fill in any more information if they so choose.The second page of the questionnaire asks for more detailed demographicdata (see column 153 of FIG. 1B) like level of education, level ofincome, culture, politics, etc. The user may quit and not fill in anymore information if they so choose. The third page of the questionnaireasks for yet more detailed background information and so on.

Once the system computes the linking distances existing (if at all)between the various users in step 528, in one embodiment, the systemalso automatically generates a linked list for each user where the listitems are sorted according to linking distance from the lead user, withthe closets one or more other users appearing first in the list and thefurthest appearing last. Thus the list provides an ordering of otherusers according to distance from the lead user of that linked list.

In step 528, for each subgroup formed by step 524, the system computesthe linking distances (if any exist) between each of the users of thatsubgroup and available, populated chat rooms belonging to the node ofthe corresponding topic. In some instances there may be noalready-populated chat rooms belonging to the node, particularly if itis a newly formed topic. However, if already-populated chat rooms existfor the node and a given user within the subgroup is determined (in teststep 530) to be within acceptable linking distance of that room (whereacceptable linking distance may be defined by user preferences or by thesystem), then control is passed to step 533.

In step 533, the subgroup member who is deemed to be within acceptablelinking distance of a on-topic room is removed from the subgroup. Inother words, if Sam 111 of FIG. 5A is deemed to be acceptably closeenough to populated room 563, then Sam is taken out of consideration forwhether he should be invited into floating room 561. This reduces thetrail and error burdens on the floating rooms process which occurs later(e.g., step 534). In one embodiment, the mere fact that an on-topic andalready populated room (e.g., 563) has been found within acceptabledistance of a subgroup member (e.g., Sam 111) does not mean that aninvitation will be sent to the user for that room. The system could besimultaneously generating many other potential invitations (chatopportunities) for the same user and some of these chat opportunitiesmay have been scored as having much shorter linking distances (in otherwords, much higher co-compatibility scores) than the current chatopportunity. Accordingly, scored chat opportunities are returned fromthe match-making subroutines that found them (e.g., via the processdepicted in FIG. 5A) to a supervising DsMS module for final sorting.(Functionings of DsMS's or Domain specific Matching Services will beexplained in more detail below. See 416 of FIG. 4A for example.) TheDsMs then decides how many and which of the highest scoring chatopportunities (if any) should be converted into actual invitations to besent to the corresponding user. Score alone need not be a determinant.The DsMS module may decide it wants to provide diversity by avoidinginvitations to almost same chat rooms. More over, the domain-specificDsMS module may be in communication with other DsMS modules (see 416′ incenter 420 of FIG. 4A as a possible example) so as to provide a balancedspread of invitations, not only for the topic nodes covered by this DsMSmodule but also for the topic nodes covered by the other DsMS modules.

Still floating users (those not yet paired to a room) who have not beenculled out from the subgroup by step 533 get passed on for processing bystep 534. Here, the process mentioned above for Sally 121 is carried outif sally is one of the still floating users. Floating room 561 isspawned for her and she is deemed the foreperson of the room. Then thelinked list that was earlier generated (in step 527) to identify theclosest other users is stepped through, and the still floating otherusers remaining on her linked list are hypothetically added into thefloating room 561 one by one with linking distance adjustments betweenthe room 561 and users being made on the fly. At some point, one or morelimits associated with the floating room will be approached, such as toomany invitees or too many relatively long linking distances, etc. Atthat point control is passed to step 536. The limits of eachhypothetically joined user to that room is also tested. It could be thatalthough the room's distance limit was not surpassed, the user'spersonal limit was surpassed. so that user is returned to the floatingusers pool in hope that some other room will pick her or him up. In step537, the still attached users are removed from the floating pool andtheir corresponding chat opportunities are handed back to the DsMS forfinal scoring and sorting. As in step 533, users whose identificationsare passed into step 537 with an associated chat room (e.g., 561) maystill nonetheless not get invited to that room. In some cases, afloating chat room (e.g., 561) may end up devoid of any potential usersother than its original foreperson (e.g., Sally). There is no point ininviting Sally alone into her own private chat room. So the trial anderror room matching gets undone in step 539 and that is the end of thetrail for that room. It is dissolved. Sally may still get picked up byanother floating room which has someone else as its foreperson (e.g.,Sandra). If not, no harm arises. Sally merely does not get an invitationas a result of this one of many match-making runs. As mentioned above,in one embodiment, room median, average or other attributes aredetermined at predetermined attribute checkpoints in time and heldconstant as such until the next checkpoint.

It is to be noted that the floating room which emerges from step 537with two or more invitees paired to it, may still never come intofruition. All of the invitees can turn down their invitations or notaccept in a predefined time, in which case the reserved but stillunfilled room is automatically dissolved. Moreover if only one user(e.g., Sally) accepts the invitation, an apology message may be returnedto her explaining that the room has been terminated in the interim(because there is no point in inviting Sally alone into her own privatechat room) and the reserved but still unfilled room is automaticallydissolved. In one embodiment, users who turn down invitations or are thelone ones accepting for an otherwise empty room are automatically addedback with their corresponding clustering data (old CFi's) into thefloating users group of a later run of step 520 so they have a chance ofbeing joined with new users also being processed by that later executionof step 520. In one variation, this add back feature is employed only ifthe age of the old CFi data sets of the uninvited or lone invited userdoes not exceed a system predefined aging limit. If the CFi data set isover aged, it is dropped. The user may get further invitations aftersubmitting fresher CFi data.

Referring back to FIG. 1B, discussion of some other weight-wisescoreable columns of the CpCCp 105 h.1 continues here. Similar to column155, the next vertical column, 156 (undesirable buddies) indicatesnegative attributes, meaning that these are data parameters identifyingusers that the local user 121″ does not want to generally find in chatrooms she is invited into. Negative score points are attributed to usersmatching these parameters. For example, user 121″ (e.g., Sally) hasindicated that she does not want to be invited into any chat room thathas the user with username “Troll” in it or “Monster”. She has alsoindicated that she does not want to be invited into a chat room whichwill include people under the age of 14 or people over the age of 19years old. The co-compatibility calculating server assigns negativescore values (optionally differently weighted) to each of theseparameters if met and therefore if a corresponding already-filled chatroom (e.g., 563 of FIG. 5A) or a corresponding floating room (561) hastoo many negative or undesirable attributes to it, the score will bevery low, the indicated co-compatibility for inviting local user 121″may be very low or even negative and corresponding very long linkingpaths (e.g., 515/551 of FIG. 5A) or no linking paths at all will result.In one embodiment, the cloud server does not invite user 121″ (bysending her a corresponding invite or Cciv) if the total score generatedby her current CpCCp 105 h.1 for the pre-existing chat room or proposedchat room group is a negative one. In an alternate embodiment, therequirement for sending out an invite (Cciv) may be higher, for examplerequiring a positive score of 10 or better.

Referring to vertical column 157 (chat room properties), these criteriaare directed to statistically averaged or other global properties forthe chat room (or proposed chat room), this being distinguished from thepositive or negative criteria attributed to individuals alreadyparticipating in such rooms. A user may leave columns 155-156 blankwhile only filling in criteria in column 157. In the illustrated exampleuser 121″ has indicated that she prefers a chat room which has ten orfewer people (or alternatively she prefers a room with a “cozy”population range of 5 to 9 participants, but no fewer or no more). Shehas indicated a preference for a chat room where the average age is 16years old. She has indicated a preference for a chat room where the maleto female mix ratio is 20% to 80%. She has indicated a preference for achat room where the average participant income is $50,000 per annum.Moreover she has indicated a preference for the mean location of theusers within the chat room to be the central portion of the USA. Onceagain the server assigns positive or negative, weighted or unweightedvalues to these qualifiers that work to respectively increment ordecrement cumulative scores for given chat room (whether alreadyexisting or proposed to be formed) relative to user 121″. The potentialinvite score goes up or down depending on how many of the desired orundesired properties are met by the proposed or preexisting chat room.

Referring back to vertical columns 154 (“mine”), 155 (desired them) and156 (undesirable them) as well 157 (users in chat), there is one classof additional demographic information that is valuable to include atleast in the “mine” column 154 if not in the other columns. This is thegeneral favorites information which is shown in box 154-7 a. Each user(e.g., 121″) may have certain system-defined “topics” of interest ortopic domains of interest which that user is generally interested in.When the match-making service in cloud 150 is trying to associate a mostlikely topic of current interest with a received CFi (or recentlyreceived plural CFi's), the match-making service can look to thefavorite Topics entries (represented by the dot in 154-7 a thatintersects with column 154) of the user's “mine” column and use that asone of the clues in determining automatically what topic the usercurrently is most interested in conjunction with the current contentareas of engaged focus. Thus, even if a given user does not have DsCCp'sfilled out for use in providing automated inferencing of the user'stopic, the favorite topics entry 154-7 a in the user's CpCCp can be usedas a clue.

Aside from listing favorite topics and/or favorite domains in box 154-7a (where same or different instances of the box apply respectively tocolumns 154, 155, 156 and 157, where for 157 it defines favorite topicsof a potential preferred or non-preferred chat room), the user mayadditionally list favorite books, favorite movies, favorite (most oftenvisited) URL's/web pages, favorite games, favorite TV shows, favoritemusic, favorite foods, etc., not only for him or herself (mine) but alsoas attributes for desired and undesired chat partners or predominantpopulation attributes of desired or undesired chat rooms. By way ofexample, a given user may list “Gone With the Wind” as her favorite bookand at the same time list the same book as being an undesirable favoriteof other users in chat rooms she is to be invited into. This in essencesays, I like “Gone With the Wind” but nonetheless I prefer not to enterchat rooms filled predominantly with others who like “Gone With theWind”.

There is often a limit as to how much detailed information can bepractically given in row 171 and its crossings with columns 155, 156 and157. For example, in one embodiment, the number of names for desiredchat buddies may be limited in column 155 to just three for a nonpremiumuser and seven for a premium user. More specifically, column 155 maylist the following desirable chat partners: (1) Name:=MBGFFL, (2)Name:=Sharon and (3) Name:=Sandra for CpCCp owner Sally (121″). Thematch-making system may be pre-programmed to score these as linearlysummed positive scores. More specifically, for each desirable chatpartner already inside a potential chat room to which the current useris to be potentially invited, increase the Invitation_score by +1. So ifonly MBGFFL is in a potential room, that room's score is increased by+1. If all three of the listed desirable chat partners are present, thenby +3. If the topic being discussed in that room doesn't closelycoincide with the topic on the current user's mind (let's call her,Sally), that room's Invitation_score by reduced by a −5. However,suppose Sally wants to secretly impose the following special condition:If a potential room include MBGFFL AND Sharon BUT NOT Sandra, I want tobe invited in irrespective of what the topic is. To this end, theknowledge-base rules set 175 may be embedded into or logically linked toSally's CpCCp of the moment, 105 h.1. The utilized knowledge-base rulesset 175 may contain the following special rule: IF Room_member=MBGFFLAND Room_member=Sharon AND Room_member=! Sandra THEN Increase thatroom's Co-compatibility score by +25. (Here, the symbol=! is understoodto mean, not equal to.) As seen the special rule is primarilypersonality based rather than topic based. Topics are topics of the room(if any topic at all, else it is deemed a “catch-all”) and not the topicwhich the current user is probably thinking about. (This is a subtledifference which will be better understood when DsCCp's are discussedbelow. It is to be noted that there are at least two different kinds ofcatch-all rooms, namely, those where even though the topics on itsusers' minds are not the same, at least the content of current focus issubstantially the same; and those where neither the content of currentfocus nor the topic on its users' minds are the same but the in-roomusers are nonetheless chatting with each other and thus perhapsconverging on a topic of common focus. In one embodiment, each chatroom's attributes are deemed to be frozen in time for regular intervals;e.g., every 5 minute stretch, 10 minute stretch, 15 minutes, etc., eventhough users may be constantly entering and leaving the room.)

When combined with the base rule of column 155, row 171, the aboveIF/THEN rule concerning who the current room members are, and are not,basically says, Sally likes each of MBGFFL, Sharon, and Sandra alone andeven more so when they appear in any combination in a room; but Sallyespecially likes it when both of MBGFFL and Sharon are present butSandra is not. Perhaps this is so because Sally feels that a specialsocial synergy exits for Sally when this particular combination ofpersonalities is present in a chat room together with Sally. Thepersonalities-directed rules set 175 may be formulated with aid of anelectronic questionnaire that Sally fills out. The data storage capacityof the personalities-directed rules set 175 may be progressivelyincreased to higher limits in accordance with higher level premiumsubscriptions that Sally pays for. Standard subscription users may belimited to having only relatively simple and smallpersonalities-directed rules sets 175 while premium subscribers areallowed greater complexity and a greater number of rules and/or morestorage space. Personalities-directed rules sets like 175 are notlimited to specifying special rules about other users. They may bedirected to personality quirks of the current user (e.g., Sally).Suppose for example that Sally does not want to be invited into Domain 5chat rooms (a hypothetical domain name) if the time is between 2 PM and5 PM and she is still at work. A corresponding rule might then read asfollows: IF Room's_Domain_Name=5 AND (Time >2 PM AND Time <5 PM) ANDMy_Location=Work THEN reduce room's Co-compatibility_score by −30.

It is to be understood that just as system limitations may be imposed onthe number of desired chat buddies who are individually listed in column155, row 171 (essentially as equally weighted members of a linearlysummed scoring value), there can be similar limits placed on the numberof undesired chat buddies who are individually listed in column 156, row171 (essentially as equally weighted members of a linearly summed andnegative scoring value). Similarly, there can be system definedlimitations imposed on the number of age ranges entered for the “Age”row of column 153 as it crosses with each of preference specifyingcolumns 155, 156 and 157. There can be system defined limitationsimposed on the number of socioeconomic class identifiers entered for the“socioeconomic class” row of column 153 as it crosses with each ofpreference specifying columns 155, 156 and 157 and so on. Theknowledge-base rules set 175 may be used to expand on these limits andprovide specialized scoring rules for specialized permutations ofvarious ones of such preference parameters, including for cross subclasscombinations. More specifically, one rule might read: IF Room's_CurrentPopulation <10 AND (Avg_Age Range is 14-17 OR 35-39) AND M/F Mix is inrange 20/80 to 5/95 THEN increase Room's Co-compatibility score by +100.

It can be bothersome for users, especially newcomers to the match-makingand invitations-generating system (MM-IGS) to fill out long electronicquestionnaires from which their respective CpCCp's can be automaticallyformulated. In one embodiment, so-called template CpCCp's and templateknowledge-base rules sets (e.g., 175) are prestored in the system forinitial assignment to new users. Each new user may be initially asked tofill out a very short demographics questionnaire (e.g., just name, age,gender and place of birth or residence) from which a stereotyping modelof the user is developed. The developed stereotyping model is used toselect for that user, one of the prestored template CpCCp's in thesystem and optionally also one of the prestored template knowledge-baserules sets. (The same stereotyping model may also be used to select forthat user, one of prestored template DsCCp's and PEEP's and optionallyalso one of prestored and respective template knowledge-base rules setsfor domain specific rules and emotional expression rules.) Then later,as each new user continues to use the system, corresponding models ofthe user's personality likes and dislikes are refined and improved overtime as are also models for the user's topic likes and dislikes and forthe user's personal ways of expressing different emotions or mind sets.The refined and more accurate models may be used to automatically pickfor and assign to that user correspondingly better matching ones of thetemplate profiles and/or template knowledge-base rules sets. Even later,as a user becomes more skilled in utilizing the match-making andinvitations-generating system (MM-IGS), the user may be empowered tofine tune his or her personal CpCCp and DsCCp's and knowledge-base rulessets or the user may employ an authorized service provider authorized bysystem administrators to perform the fine tuning for that user.Additionally, background fine tuning service running automated in thebackground of the system may analyze trending data about the user andfine tune his or her rules even more. By way of example, suppose theuser named Sally has created for herself a CpCCp rule (175, item 3) thatsays: IF Room's_Domain=Celebrity_Gossip and MBGFFL is a member insidethe room THEN increase that room's co-compatibility score by +100.However, on analyzing Sally's actual behavior as stored in the system'strending storage (437 of FIG. 4A), a background fine tuning servicedetermines that Sally fails to accept invitations to a room whose domainis Celebrity_Gossip and where her best friend for life is already insidethe room much more often than is warranted by a score increase of +100.In other words, the system is wasting its time and resources sendingSally invitations to a matching room like that. A more realisticincrease of score for the potential room's co-compatibility score wouldbe +50. In one embodiment, the fine tuning service alters the aboveIF/THEN rule so it says THEN increase . . . by +50 rather than +100. Inan alternate embodiment, the fine tuning service compromises between therealistic score change and the user's exaggerated score increase byautomatically modifying the above IF/THEN rule so it says THEN increase. . . by +75 rather than +100. Later, it may compromise again by pickingan increase of +65 as the median between +75 and +50. In this way ifSally starts accepting substantially more invitations for that specifiedkind of room, the modified rule will not be far off from her long termnorm.

Unlike the demographics data 171 in vertical column 154 (“mine”) of FIG.1B, the reputation data 172 and credentials data 173 of vertical column154 are not directly controllable or specifiable by user 121″ (e.g.,Sally) to whom those reputation and credential indicators areattributed. They are not self-generated. Instead they are developed overtime through community determinations such as by votes cast by trustedother users in the system (when those other users are of sound mind)and/or by validation by the system operator. In one embodiment, eachuser (e.g. 121″) is given 3 free reputation files which define variousreputation attributes of the user when seen as a general person (G) oras a professional person (P) acting in their primary professionaloccupation or as an alleged expert or novice in a particular firstdomain and topic area (Topic A). In one embodiment, if the user 121″wishes to have additional reputation files for other topics inserted inher CpCCp, she must pay for having these additional reputation filesopened in various additional topic areas such as B and topic C. Sincethe reputation files for column 154 of the current CpCCp remainrelatively unchanged despite possible change of current mood by user121″, the mine reputation area 154/172 and also the mine credentialsarea col. 154/row 173 of one embodiment contain pointers to externalfiles or database records rather than containing the file datathemselves inside the CpCCp. In this way the same data for reputationmay be used from one CpCCp 105 h.1 to the next 105 h.2 irrespective ofchange of user's mood, surrounding, etc. By way of example onereputation value assigned to user 121″, in her general person role (G),by other users who have voted on this attribute indicate that user 121″likes to argue a lot. This is recorded in her general personalityreputation file (G). Alternatively, the other users may have voted toindicate that user 121″ in her general person role tends to be tooagreeable or tends to rely on things that are not fact-based. Invertical column 155, user 121″ has indicated that her desirable chatbuddies should be others whose reputations indicate they like to argueand they tend to present their arguments with fact-based backup. Invertical column 156, she has indicated that she does not want to joinwith chat buddies whose reputations flag them as being too agreeable oras debating on a basis other than a fact-based ones (e.g. on emotionalbasis instead). Although vertical column 157 for row 172 has been leftempty, it is within the contemplation of this disclosure that user 121″may also indicate general chat room properties for reputation,credentials and so forth in the general person category, theprofessional category, and specific topic-based categories. In oneembodiment, other users are blocked from voting on a first user'sreputation and/or credentials when the system determines from biometricdata collected from those other users that their current emotionalstates are such that their vote on reputation and/or credentials may notbe trustworthy. For example, the other users may be overly-tired at thetime, cranky, not fully alert and thus not in possession of fully soundminds at the moment. Hence the system can decide to not trust theirvoting judgments at such times (when voting on a first reputation and/orcredentials or voting on something else of importance to systemoperations). In one embodiment, rather than fully blocking votes ofother user who are captivated by strong emotions at the moment, thesystem proportionally de-weights their votes according to the extremityof their user emotions (the emotions determined from biometric data). Inone embodiment, if trustworthy biometric data for judging user emotionor irrationality is not available, then trending data alone may be usedfor determining that a given user is behaving out of normal during agiven time period and for responsively discounting or down-weightingthat user's votes during times of apparently abnormal behavior. Morespecifically, if the given user is submitting a significantly largerthan average number of negative votes during a given time period (e.g.,last 4 hours) then it could be automatically assumed by the system thatthe person is unusually not in a good mood and the votes should bediscounted. (Of course if the user routinely casts a large number ofnegative votes and that is the user's normal pattern of behavior, thenthis discounting feature may not kick in. On the other hand, the systemmay include an automatic vote down-weighting factor for negative votescast by users who are routinely negative and perhaps an automatic voteup-weighting factor when such routinely negative persons cast a positivevote.

While reputation is generally earned as a matter of popularity, (votedon by either credentialed voters or non-credentialed voters and/or or byeither voters with high reputations or with low reputations when intrustworthy states of mind), credentials and subject matter proficiencyare another matter. Credentials (horizontal region 173) are mostlyfact-based attributes of the given user. Credentials may define forexample, what the educational qualifications of user 121″ are, whatschools she attended, what grades she got, etc. These attributes can bevalidated by obtaining official transcripts from credential giving andvalidating authorities. In one embodiment, users have to pay servicefees to the credential giving authorities in order to have their listedcredentials displayed as having been validated to one validation levelor another. Accordingly credentials may be of an officially validatedtype as well as of an unvalidated type. In one embodiment, each usergets 3 free nonvalidated credential files, for example, one relating totheir educational background, one to their work resume or experience,and a third related to a firstn-chosen topic (A). Additional fees mustbe paid to the system operator to support additional credentials forfurther topic areas and also to support validated credentials as opposedto unvalidated ones. Proficiencies are determined based on communitystandards and community cast votes in different domain and topic arenas.

For some users, credentials (row 173) may be the most important type ofpreferences to indicate for being invited into a given chat room or not.Some users may prefer to deal only with chat rooms that contain otherpersons who are equally credentialed in a specific topic (e.g. topic B)and to have validated educations at the masters' degree level or higher.In the illustrated example, user 121″ has indicated in vertical column157 that the desired chat room credential properties should be that ofthe lowest educational level being a validated high school graduate andthe highest being a master's degree. Additionally she has requested thatthe chat experience of those being invited to join with her into anby-invitations-only chat room be ones who indicate little or noexperience with chat rooms. Additionally, user 121″ has indicated aparticular superior to subordinate participant mix. Most specificallyshe has requested that the 70% of the people in the chat room that sheis invited to join (or host) should have peer credentials similar to herown and 20% may have superior credentials while only 10% or less haveinferior or subordinate credentials. She has requested to be consideredas one of the peers. (Complex invitation criteria, by the way, may bespecified in rules set 175 rather than in the main body of the CpCCp.)Alternatively she could have requested that she be considered asubordinate user and that one or more persons with superior credentialsshould also be in the chat room to advise her on an area in which she isnot an expert. Alternatively she could have requested that she bedesignated as a superior credentials or proficiency member of the groupand everyone else be of a subordinate credentials class. Thesepreference options can be very important because it allows the user 121″to control the type of interchange that will occur in the chat room sheis invited to join (or that she indirectly invites others to join). Forexample, if she wishes to obtain advice from other chatterers who havesuperior credentials in a particular topic area (e.g. Topic C) relativeto her credentials in that topic area, then she may ask for a mix whereshe is part of the subordinate participant class. On the other hand ifshe wishes to converse with people of equal credentials to her own, thenshe may insist that most people in the chat room (e.g. 70%) includingherself be of a specified peers class. Similarly, an expert in aparticular field, say financial advice, may wish to chat only withpeople with lower credentials for the purpose of providing them withfinancial advice (perhaps for a fee). In this case that person woulddesignate himself as the sole member of a superior credentials classwithin the group and allow for 99% subordinates (e.g., novice class) andalso control the size of the group so as to keep the conversation smalland controlled.

In general, it may be seen from FIG. 1B that each user may control thetype of chat room invitations they receive from the cloud 150 based onhow they fill out their current personality-based chat compatibilityprofiles 105 h.1, based on what reputations they have earned throughgeneral use or in topic-specific arenas, and based on what credentialsand/or proficiencies they have established on an unvalidated basis or ona community-validated basis.

Thus far, for users 121′, 131′, 141 it was assumed in FIG. 1A thatcommonality of eyeball focus (and/or other indication of attentivefocus) on a same magazine article (e.g., 127 a, 137 a) was enough toindicate commonality of interest and enough to warrant automaticallyinviting users 121′, 131′, 141 into a same chat room 161. However, thereare at least two alternate possibilities. First, two users (say 121′ and131′ again) are mechanically focusing on a same piece of computer-outputcontent (e.g., 127 a, 137 a) but in their minds they are considering twoentirely different topics. One for example may be reading about acelebrity Britney visiting a beach in Rio de Janeiro, Brazil andthinking about travel plans to the same destination. The other user maybe thinking about what other celebrity is known to be in the same areaat the same time and if it is more than mere coincidence. Thus samecontent but two entirely different topics or domains of interest. Thereis no apparent benefit to inviting these two users to chat with oneanother. The match-making service should be generally able to avoidinviting into a same room, users whose current topic of interests arevery divergent from one another. The other situation is where two usersare indeed respectively thinking about a same topic, subtopic, etc. butare mechanically focusing on respectively different content offerings(e.g., one looking at Celebrity Sensations Magazine and the other atHollywood Star Gossip Magazine (which here is taken as a fictitious namefor a possible online magazine and is not to be confused with any realmagazine of same or similar name if any exists). Thus in the second casethere may be benefit to automatically joining these two users forchatting with one another even though they are focusing on differentcontent (for example on web pages having different URL's).

FIG. 1C shows a possible data structure for part of a Domain-specificCurrent Chat Compatibility Profile or DsCCp 106 h.1 for short. The DsCCp106 h.1 of a given user 121″ may be used in cooperative combination withthe CpCCp of that same user 121″ to automatically home in onco-compatible chat buddies or chat rooms and to responsively generateinvitations into corresponding chat rooms (e.g., 161 of FIG. 1A) basedon domain or topic. In one embodiment, DsCCp's 106 h.1, etc., areorganized into a hierarchical tree structure that somewhat mimics ahierarchical tree structure used in the cloud 150 for keeping track ofdomains and topics. By this, it is meant that each user will have a rootDsCCp and may have under that root various child or branch DsCC profileslinked to one another in parent child relations. Not all chat rooms haveto be logically tied to a specific topic or domain orDomain/topic/subtopic/ . . . /etc. hierarchical designation. Some roomsmay be defined as not yet having an ascribed domain and topic. Thesewill be catch-all rooms. However, for cases where users prefersubdivision of chat rooms according to domain, topic, etc., the systemmay rely on the user's DsCCp's for performing one or both of at leasttwo functions: (a) automatically determining the user's more probablecurrent topic or topics of interest and (b) automatically homing in onco-compatible chat buddies or chat rooms for the determined topic ortopics that are probably currently of common interest. As in the casewith PEEP's and CpCCp's each DsCCp may have embedded therein orlogically linked to it a topics-directed set of knowledge-base rules(195). Unlike rules 175 of FIG. 1B however, the knowledge-base ruleshere (in 195) may be used to define what topic the current user mostlikely has on his or her mind. This is done by looking at CFi hints andthen scoring those hints. More detail will be provided when FIG. 4C isdescribed.

A Domain-specific Chat Compatibility profile (DsCCp) such as the one 106h.1 shown in FIG. 1C can be viewed as a personality-free extension of,or substitute for, the user's general, personality-based current chatcompatibility profile (CpCCp). While the general current chatcompatibility profile (CpCCp) operates primarily to specify the user'sgeneral personal and personality directed characteristics, such as age,educational level, etc., as well as the their preferences for same ordifferent general personality characteristics in chat partners and alsotheir general preferences for favorite topics, favorite books, authors,movies, etc. (or most disliked topics, books, authors, etc.), theDomain-specific chat compatibility profiles (DsCCp's) take suchselection preferences one step further (or along a different preferencesplane) by specifying a user's chat compatibility profile on a per Domainbasis or per Domain/topic/subtopic basis. The utilized domain, topic,subtopic, etc. names or aliases are the same as, or are mapped to matchthose used in the system's stored hierarchal tree of domains and topics(see briefly FIG. 4B). Selection of a given user's CpCCp and/orDsCCp('s) as being “current” can change depending on personal variablessuch as the client user's current mood, his or her surroundingenvironment (e.g., work versus home), etc. Unlike the CpCCp which tendsto be general in nature and primarily personality based, each DsCCp ismore so proficiency or interest directed to a specific domain or topicnode within a hierarchal tree filled with parent domain nodes and childtopic nodes. For example a person might indicate that they are a 50 yearold with a Master's degree in Business Administration (MBA) and, in sofar as personality is considered, they are generally happy to chat withanyone within 10 years of their own age and with at least a high schooldiploma as educational background. That general specification wouldnormally be part of their general CpCCp and would be used even if theuser is being invited into a catch-all room that has no specific domainor topic associated with it. This same user might also indicate (e.g.,in section 154-7 a of FIG. 1B) that their usual or favorite Domain ofinterest is the Domain of finance. The same person may wish to specifythat when they are chatting under that finance Domain (as opposed to ageneral interest other type of Domain or a catch-all Domain) they onlywant to chat with other people holding at least a master's degree if nothigher (hoping to perhaps get better advice or exchange ideas at theirlevel of advanced proficiency). Alternatively, if the interest Domain isthat of music, the same user may want to chat only with people who are10 years younger than they are (because nobody in their own age groupappears to appreciate the newest music trends). The same user (e.g.,121″) might also indicate that a less usual but still predominant Domainof interest is the Domain of movies and that they only want to chat withpeople older than they are (because they like older classic movies).Rather than placing these personality-independent, domain by domainspecific preferences in the general CpCC profile, in one embodiment suchdomain specific preferences are stored either in one all encompassingDsCCp record or in separate DsCCp's which are logically linked to a rootDsCCp and to each other according to a logical tree structure where aroot DsCCp record lists the hierarchically higher domains and theirorder of current probability (as ordered for example at the top ofcolumn 183 of FIG. 1C with highest likelihood being number 1, lowestnumber 7). Child DsCCp records may provide additional rules (e.g.,listing of primary keywords such as in column 188) for each specificdomain and topic under that domain and subtopic under the topic and soforth. It is possible for the plural DsCCp's of a given user to overlapand perhaps conflict with regard to likes and dislikes (preferences) ofthat user. In such a case, the match-making and invitations-generatingsystem (MM-IGS) determines which of the DsCCp's currently takes prioritybased on currently detected mood or surrounding environment of the userand/or based on trending data stored in the system's Trending Data Store(e.g., 437 of FIG. 4A). In one embodiment, the most probable topicscurrently on the user's mind are determined first and only thereafter isa deeper search performed for chat rooms that not only match or comeclosest to the user's probable topic of interest but also match or comeclosest to the user's personality based preferences. Of course, it iswithin the contemplation of the disclosure to do the vise versa incertain circumstances, namely, search for the most co-compatible roomson the basis of personality first and then refine the search on thebasis of topic matching. Hybrids of the two approaches are possiblealso.

More to the point, a root DsCCp such as 106 h.1 in FIG. 1C may have afirst table (or other database structure) indicating that currently user121″, if they are at all thinking about a specific topic and there areno narrowing hints provided by the CFi's, it will most probably benational politics (rated number 1 because for example a Presidentialelection is taking place during the current year) and it will next mostprobably be a finance domain identified as Finance.002. (There coulddifferent kinds of Finance domains identified for example asFinance.001, Finance.002, . . . Finance.999; each with unique subtopicsas children of its hierarchy tree.) There are certain topic-narrowinghints or clues 188 that may be picked up from recently pulled CFi's 128a′ as to what the user's current domain and/or topic, subtopic, etc. ofinterest is. Say for example that the user's recent web browsing historyincludes the web site named Wall.St.J.com (here a fictitious name) asone of the top three most recently visited sites. That can be taken as ahint that the user 121″ is currently focused on the Finance.002 domainbecause table 183 indicates that this domain is highly likely andfurther because the Wall.St.J.com entry in table 185 is logically tiedto a probability weighting pointer (not shown) that shows, say, 75%probability of linking to the Finance.002 domain if Wall.St.J.com is inthe top three of recently visited sites by that user 121″.

Yet another of the topic-narrowing hints 188 provided by the user's rootDsCCp 106 h.1 may be a collection of recently used search terms enteredinto a search engine. Say for example that the user's recent searchhistory includes the search term “economy” as one of the top three mostrecently used search terms. That in combination with DsCCp entry of“economy” in a corresponding row of column 186 can be taken as a hintthat the user 121″ is most probably currently focused on either theFinance.002 domain or the Politics domain. This may be so if table 183indicates those two domains as the most highly likely two tied to the“economy” search term entry placed in table column 186. The illustrated“economy” entry may be logically tied for example to a first probabilityweighting pointer 186 b that shows 48% probability of linking to theFinance.002 domain, a second pointer (not shown) indicating 47%probability of linking to the Politics domain and further pointers (notshown) with 5% weight distributed to other domains.

Weighted pointers are way of linking keywords to most probable domains.A more flexible approach to determining what the more probable domainand topic of interest is uses a set of knowledge-base rules such asshown at 195. In one embodiment, topic likelihood scores are madefunctions both of the one-to-one horizontal correlation hints providedin columns 185 and 186 as well score adjustment rules specified in theDsCCp knowledge-base rules set 195. More specifically, reading acrosssubrow 4 (“Poker”) of row 191 of FIG. 1C, for the current user, the mostfrequently associated URL with this “Poker” domain is shown in acorrelated row to be “PokerGuru.com” (a fictitious name here) and themost frequently associated search keywords are shown in a correlated rowto be “cards” and “table”. A further column (not shown) might specifythat for the current user, the most frequently associated meta-tags withthis “Poker” domain are <<eye-tells>> and <<card-shark>>. Accordingly,if current content being focused upon by the user appears under the URL,“PokerGuru.com” and the same user entered one or more of the searchkeywords “cards” and “table” in a recent stretch of time into his searchengine and the current content being focused upon also includes one ormore of the meta-tags <<eye-tells>> and <<card-shark>>, then each ofthese coincidences is linearly added as a positive factor into a topiclikelihood score stored by the system. Scores for competing topics(and/or competing domains) are sorted and the ones with the highestlikelihood scores are assumed to be the most likely topics on the user'smind. However, there may be special scoring synergies to be invoked whenunique combinations of hints appear. For example, in a JSON-likeexpression which allows for different types of URI's (Universal ResourceIdentifiers) including the URL identifier type, the rule might read asfollows: IF URI:=URL:=NYTimes.com AND MetaTag:=election ANDMetaTag:=economy THEN increase likelihood score ofTopic:=National.Politics/Presidential_election/economics_debate by +100AND increase likelihood score ofTopic:=City.Politics/Mayoral_race/economics_debate by +50. This kind ofspecial treatment rule would go inside the knowledge-base rules set 195of the operant DsCCp (which could be a root DsCCp or a child DsCCpstored under the root).

Data in the DsCCp's may be adaptively changed over time as the user'spreferences change. For example, the ordering of domains (column 183,major row 191) may be changed to reflect different preferences in casewhere no additional hints (no keywords, no URL's etc.) are available.The more frequently associated URL's, keywords, meta-tags for eachlisted domain or topic of column 183 may be changed in response todetected changes of the user's preferences over time. One of thefeedback mechanisms used for automatically detecting such changes iswhen the user turns down initially offered best-guess invitations andinstead accepts an invitation with a substantially lower likelihoodscore. That tells the system that the user's mapping of hints to likelytarget topics have shifted.

Table column 184 indicates a length of user history associated with eachdomain and optionally includes pointers to history records for therespective domains and what priority positions they held in the past. Ifthere is long history of one domain being in the top three for example,then this historical trend may generate a sort of inertia for domainreordering algorithms which works to keep the top three domain with longhistory of being there from suddenly being dropped say out of the topten list. The illustrated domain and topic picking structures of FIG. 1Care merely examples and it is understood that the DsCCp may have more,others or various further permutations of columns, sub-columns, rows andsub-rows, etc. Moreover, it is understood that like the case for theuser's CpCCp, the identification by the system of the user's currentroot DsCCp (and thus its associated children DsCCp's) may change shiftas an automated function of the user's detected mood and/orsurroundings.

In addition to domain-narrowing hints such as shown at the top of majorcolumn 188 for main topic domains, the root or a child DsCCp may includehints such as shown at major rows 192, 193 for specific topics orsubtopics under respective domains or topics. Thus the DsCCp may be usedfor automatically homing on the most probable topics of current interestby the given user.

As mentioned above, users may have weighted preferences (likes and/ordislikes) on a domain by domain or topic by topic basis, on a chatpartner by partner basis (different weights for different partners,e.g., positive scores that involve MBGFFL get a +1.3 multiplying boostfactor just because MBGFFL is Sally's best friend for life; and negativescores involving MBGFFL get a 0.9 watering down weight for the samereason). Users may also have weighted preferences on a room type by roomtype basis (e.g., if a potential room is limited to a range of 3 to 5participating members, its positive co-compatibility scores areautomatically boosted by a +1.5 multiplying factor because Sallyconsiders this population range to be a sweet spot).

In one embodiment, in-profile weights are automatically updated based ondeterminations made by the system's trending data monitoring services.In other words, a given user (e.g., Sam) may expressly record that heprefers to chat with people his own age. However the system's trendingdata monitoring services may determine based on actual historical dataregarding his chatting activities that he actually doesn't care so muchabout age and instead most prefers to chat with people who are historyenthusiasts. In this case, a weight given to age may be automaticallydecremented while a weight given to history being a favorite topic maybe automatically incremented in Sam's system-stored profile(s).

In FIG. 1C, an example of specification of preferences for chat roomproperties for a given Domain/topic identified hierarchically as XYz(domain=X, topic=Y, subtopic=z) is shown at column 187. Alternatively,this type of room qualifying rule could have been embedded inside ofknowledge-base rules set 195. One of the Domain specific preferencesettings is the notion of proficiency in the given topic. At the CpCCplevel a person's education level might provide an indication of generalchat compatibility, but a person's general educational level may notindicate a level of proficiency in specific topic areas. A person mayhold a doctorate, in marine biology for example, but he may be a noviceat quilting. DsCCp's can allow proficiency levels to be expressed on aper Domain or topic node basis as indicated at 187. A given domain nodemay have first proficiency preferences attached to it by the user and asubtopic node under that domain may have other (e.g., more stringent)proficiency preferences attached to it by the user. Additionally, interms of narrowing down on the more likely topics on the user's mind, agiven domain node may have first user-preferred keywords or key-phrasesassociated therewith and stored in the user's root DsCCp while asubtopic node under that domain may have other (e.g., more specific)keywords or key-phrases that are frequently used by the given user(e.g., Sam) and usually intended by the user to refer to that subtopicnode. Alternatively, such topic narrowing specifications may be definedby IF/THEN rules in the knowledge-base rules set 195 of the DsCCp. Morewill be discussed regarding identification of the more likely domainsand topics on a user's mind further below. The above discussion was justan introduction as seen from the single user's perspective. In oneembodiment, users can query the network to view their personal CpCCp'son a mood by mood basis and their DsCCp's on a topic by topic basis inorder to determine if these profiles appear to accurately define theuser's preferences and/or other profiled attributes. In one embodiment,domain specific compatibility profiles (DsCCp's) are computer readabledata files (each accessible by the corresponding logged-in user andpartly modifiable by the respective logged-in user) that providepreference information and likelihood of match information for specificdomains and/or topics. Reputations and credentials may be stored inDsCCp's rather than in the CpCCp's.

Referring to FIG. 2A, shown now in more detail is a first mechanismwithin a local computing machine (client) 211 for managing thetransmission of current focus information packets (and current interesthints) to servers within cloud 150. More specifically, machine 211includes a current focus and interest clues data collector 205 a, acurrent focus identifying records generator 206, a CFi records storingbuffer 215, and a CFi records puller 207. The focus clues data collector205 a is operatively coupled by way of one or more couplings 204 (e.g.,wired or wireless) to a corresponding set of one or more focus detectors203. The focus detectors 203 can include sensors such as web cameras,biometric sensors, etc. that sense focus and/or biometric states of theuser, and data extractors that extract data indicating for example theidentity and/or source content of presentation content being apparentlyconsumed by the user. The focus detectors 203 may also include settingdetectors that sense settings of the other sensors such as an aperturesetting of a web camera for example. Examples of data that may beextracted by the data extractors include: a URL held in a web browser'starget address field, a file name and file access pathway held in awindow's source address field, markup source code (e.g., HTML, XML code)used to generate a presented web image, etc. The couplings 204 may bewired or wireless. Data collected by the current focus and interestclues data collector 205 a may include current focus detector settingsas well as the focus clue data collected by the focus detectors.Examples of settings may include camera angles and web page stylesheetsthat control how a web page is displayed. The structure of a Currentfocus identifying packet (CFi) is shown in exploded view for oneembodiment in the magnified example. This is just an example and CFipackets in general may be smaller and simpler or larger and morecomplicated. In the illustrated example, each CFi packet contains afirst field 215 a identifying the user by a unique username and/ornumber for example. A second field 215 b identifies one of possibly manylocal sensors or other devices from which focus clues are being obtainedin addition to the local machine 211 to which a corresponding invitationis to be sent if the invitation is generated in response to CFi databeing sent. In one embodiment, the focus clues providing sensors (e.g.,116) are integrated within the user's primary local machine 211 (e.g.,in its housing), in which case the machine ID's field 215 b may containjust one machine identification rather than separate ones for theto-be-invited machine and for the focus data supplying device (e.g.,116) It is possible for a single user to be operating multiple machinesat a time and therefore it is important to know which devices ormachines generated which CFi's and which machine is to receivecorresponding invitations. One reason is so that correspondinginvitations can be routed back to the correct machine (e.g., 211) amongthe user's plural active machines. A third field 215 c indicates thegeographic location(s) of the one or more machines identified in field215 b. Location may be provided by a GPS unit integrated in the user'sclient machine. Provision of the user's current location may beimportant for cases where chat opportunity co-compatibility relies onthe user's primary local machine being within a given geographic regionor specific location or being surrounded by a specific environment. Forexample, the user may be in a moving car (say driving cross country tothat Las Vegas convention of poker players) and the user may want tothen chat with geographically nearby other people who are also headingto the same Las Vegas convention. Alternatively, the user may already beat the convention and open to meeting in person with another user who isalso there and has one or more topic of current and common interest onmind. Also various sensors may be moving relative to the user orchanging their settings over time. Various other clue data extractorsmay be changing their settings over time. Field 215 c may thereforeprovide not only changed locations data but also changed settings data.In one embodiment, the user's client machine periodically uploads to thecloud, simple CFi's that merely indicate the user's ID (215 a) and hisor her current GPS determined location (in field 215 c). A further field215 d provides one or more current time stamps in terms of GreenwichMean Time (GMT). By supplying the time stamps for each current focusindicator (CFi) in GMT form, it is possible to quickly match users whoare generating common focus indicators in the same global time frameeven though they may be located in different geographic areas. Moreover,as mentioned above, it is sometimes desirable to integrate data from aplurality of CFi's that were generated within a specifiable stretch oftime; for example so as to link a content related event with alater-in-time emotional reaction to that content. There are at least twodifferent kinds of time stamps that may be stored in field 215 d,namely, the time the data was obtained by a corresponding sensor or dataextractor and the time the data was recorded by a below described recordgenerator 206. In some instances the delay between the two differentkinds of time stamps may be important for determining what weight is tobe attributed to the CFi provided data. some data may be stale and thusgiven a low or null weighting. The CFi data collector 205 a alone or incombination with focus detectors 203 may be configured to identify atleast one of: (a) a web site from which the focused upon content wasobtained; (b) a communications channel from which the focused uponcontent was obtained; (c) a data file storage location from which thefocused upon content was obtained; (d) another resource pathway definedbetween the user's content presentation device (e.g., 117) and a uniquecontent providing resource and from which the focused upon content wasobtained where knowledge of the resource pathway helps to uniquelyidentify the content itself; and (e) a unique pointer pointing to aunique source from which the first content was obtained where knowledgeof the unique pointer helps to uniquely identify the content itself.

The current focus identifier or indicator (CFi) may come in a variety oftypes. Type of indicator is specified in data field 215 e. A number ofexamples are given although these are non-limiting. It is possible forone CFi packet to contain plural sets of fields like 215 e, 216 a-216 g,215 f-215 h all covered by a same time stamp 215 d and one digitalsignature 215 i. A current area of focus may be identified by providingonly a URL (Universal Resource Locator) for a web page that the currentuser happens to be looking at. (Or as will be seen in FIG. 3A, it mightbe another kind of file identifier 320 a or a snapshot of content 320 b,320 c found in that file or frame.) Alternatively, as partially shown byexample 216 b, the focus identifier may be the combination ofidentifying a specific frame in a given URL plus one or more keywordswhich the user has recently entered into an active search engine (e.g.,an open Google.com results window—see 330 of FIG. 3A). Thus this example216 b collects more detailed focus information as well as collectingpossible clues for determining or hinting at current topic of interestthat is likely to be on the user's mind. Alternatively as shown inexample 216 c, the focus identifier may be constituted by a URL (or filename) in combination with a snapshot of certain content found inside thepage or frame identified by the URL (or file name). The snapshot contentmay have been automatically selected based on a dwell over or otheractivity by the user's mouse and/or the user's eyeballs (detected forexample by web cam 126 in FIG. 1A) over an area containing the snapshotof certain content or it may have been manually selected by the user isresponse to a pop-out dialog box (e.g., “Please highlight key passage”).This type of detailed information 216 c allows the match-making systemto better discover exactly what part of the web page or frame or filethe user is focusing on and also perhaps the level intensity of focus onthat specific part. Yet another identifier of the likely topic ofinterest may be based on one or more keywords alone that have beenentered recently into a recently active search engine window as show at216 d. This information may be parsed and combined with identificationof content focused upon as provided by a later supplied CFi. In anotheralternative 216 e, the focus indicator may be defined by a combinationof one or more keywords plus a snapshot of results content obtained froma search based on the associated one or more keywords. In yet anotherexample, 216 f certain meta-tag codes may have been embedded in an openweb page (see also 127 b of FIG. 1A) to provide hints (clues) regardingcorresponding various topics/subtopics/etc. and/or domains of interestor to directly indicate a specific location in a global hierarchy treeof domains/topics/etc. The utilized meta-tag code or codes and theirtypes (e.g., search engine, hierarchy navigation, etc.) are included indata field 216 e of the to be uploaded CFi packet. Box 216 g indicatesthat there can be many other codes beyond 216 a-216 f for identifyingthe type of focus indicator plus the associated clues for determiningprobable topic of interest and/or intensity of interest. Examples 216a-e are merely for purposes of illustration. Aside from identifyingfocused upon content, a CFi may provide time stamped biometric data thatcan be associated with content identified by the same or achronologically nearby CFi.

Because the actual focus and/or topic-of-interest indicating data field(as opposed to its type) may be of varying length or of multiplepackets, a data length indicator 215 f is provided within each CFipacket for indicating length of a current data field and/or a number ofmultiple packets or records through which the data field continues andperhaps where the last character is found. In other words, thereferenced data field, 215 g (which contains the indicator data whosetype has been specified in field 215 e) may be fully contained in thesame single record as length indicator 215 f or it (215 g) may extendthrough plural subsequent records or packets. Following this variablelength field 215 g, is the specified data field 215 g. Additionally, oneor more biometric data points and/or intensity indictors (alongdifferent dimensions, e.g., emotional versus topical) may be provided infollowing fields such as 215 h. In one embodiment, the biometric datapoints and/or intensity of interest indicator(s) 215 h may be eachexpressed as a whole number selected from a prespecified range, say1-10, to indicate for example how strongly the user is interested,emotionally or otherwise in the identified topic area (for example theone whose identification and intensity is based on associated mouseactivities and/or eyeball activities). Alternatively other forms ofmeasurement for biometric data points and/or level of focus and/orinterest indication may be used including positive and negative numberranges expressed in scientific notation form or otherwise. To preventcurrent focus indicator packets (CFi's) from being spoofed by users ormachines other than the ones identified fields 215 a, 215 b a digitalsignature 215 i covered by a user password (e.g., hashed) may be used tocover one or more of the fields in the CFi packet and to thereby assureits authenticity. The cloud system 150 securely stores the user'spassword so that generally speaking, only it (and authorized systemadministrators) and the user know the passwords. When the user logs intoher local machine 211, she may be asked to supply the password and thisis used to form the digital signature, for example by hashing packetdata with the password. In one embodiment, although not shown, the cloudsends a random piece of additional data to the local machine duringlog-in and this random data is combined during a logged-in session withthe password so as to assure that the password cannot be reverseengineered from the digital signature. In one embodiment, the clientmachine includes face recognition software and/or fingerprintrecognition software and/or iris pattern recognition software foridentifying the user currently operating the primary likelihood clientmachine. In one embodiment, the client machine automatically presortsthe recent CFi's posted onto buffer 215 according to biometrically orexplicitly detected level of interest so that recent CFi's with thehighest degree of user expressed or inferred interest are presentedclosest to the output pointer of the buffer and thus pulled (207 b) bythe cloud first and given preferential treatment in this way over CFi'sthat are associated with substantially lower levels of user interest oruser engagement with their content.

As the cloud system 150 scales to have larger and larger number of users(e.g., clients), it becomes possible to have millions of client machines(e.g., 211) arbitrarily uploading (e.g., requesting pull up of) theircurrent focus/interest indicators (CFi's) in unsolicited manner into thecloud with the expectation of instant servicing. To avoid thispossibility, it is preferable for the cloud 150 to control the rate atwhich it acquires current focus indicators (CFi's) from different usermachines and/or for different domain and/or topic areas. In oneembodiment, all current focus indicators (CFi's) generated by thegenerator 206 of client 211 are stored on a scrolling or circular buffer215. The cloud 150 does not necessarily pull all new CFi's out of thebuffer 215 at one time. Instead, the cloud 150 sends periodic CFi-PullRequests 207 a to records puller 207. (In one embodiment, the CFi-PullRequests 207 a are preceded by the client machine 211 sending a bufferstatus reporting packet to the cloud 150. Such a buffer status reportingpacket (not shown) indicates how much uploadable buffer content isavailable and its nature. The cloud then responds in a form of ahandshake by downloading the CFi-Pull Request 207 a.) The CFi-PullRequests 207 a may contain filtering criteria for selectively pullingonly those recent CFi's whose time stamps correspond to a certain timespan and/or for CFi's whose topic hints correspond to a certain topicarea or domain of interest and/or constitute a limited number N of mostrecent ones of such criteria matching CFi's that are to be pulled. Inresponse, the puller 207 scans the local buffer 215 for CFi records thatmatch the CFi pull request 207 a and it uploads via path 207 b only theCFi's that match the pull request 207 a. In this way, the cloud cancontrol the rate at which current focus/interest indicators (CFi's) arepulled from individual client machines and also it can limit the topicarea(s) or other attributes of the selectively pulled CFi packets. Inone embodiment, the puller 207 periodically uploads a pinging packet(not shown, sent for example once every 2 minutes) to the cloud 150indicating “I am here and I want a pull request from you” where thepinging packet identifies local machine 211. If the cloud 150 (and inone embodiment, an AARMS portion of the cloud—described later) does notreceive such periodic pings for more than a predefined length of time(say 5 minutes), it assumes that the client machine 211 has been turnedoff or has gone into an interest_monitor=off mode (see 312 of FIG. 3A)and the cloud 150 then stops sending CFi pull requests 207 a to theclient machine thus conserving system resources. If and when the clientmachine 211 later resumes sending “I am here” pings (not shown, butwould be over communication channel 207 b) to the cloud, it may benecessary for the client machine to reestablish a log-in and/orservicing relation with the cloud because earlier used cloud resourceshave already been re-allocated to servicing other client machines. Thiswill be detailed when the AARMS portion 411 of FIG. 4A is detailedbelow.

Within cloud 150 there may be a plurality of different types of CFipulling servers (or virtual services, not all shown) such as 151 a and151 b of FIG. 2A. In the below detailed discussion of the cloud, suchCFi pulling services may alternatively be referred to as AARMS, orRemote Activity Monitoring Services 150 a. In one embodiment, CFi's ofusers who do not pay for a premium service are pulled only by a standardpull rate server/service such as 151 a where the standard server 151 ais allotted a first CFi pull request rate A per user. Pull rate A islower than one or more premium pull rates B, C, etc. associated withpremium services or service servers such as 151 b. Both ofservers/services 151 a and 151 b may forward copies of sampled and/orfiltered ones of their pulled CFi records to a targeted advertisementserver/service 151 c. The targets advertisement server 151 c may forceusers of the system to view corresponding advertisements, or may providethem with an option of viewing a certain number of advertisements at agiven advertisement display rate which could be a standard one (A) or apremium one (B) where the premium service has a fewer number of ads persession or fewer other intrusions. Once again, users may be asked to payfor a premium service that offers a lower rate or zero rate ofadvertisements forced onto the user. The sampled ones of the pulledcurrent focus records (CFi's) inform the targeted advertisement server151 c of the current focus and probable interests of the users fromwhich they are pulled and thus the targeted advertisement server mayautomatically adapt itself in real time to match the current interestsand moods of users to which it is sending its targeted advertisements.Moreover, the targeted advertisement server 151 c may control thefilters used in pull requests 207 a that are sent by the cloud 150 todifferent ones of the users. Accordingly, the targeted advertisementserver 151 c may control the rate at which different kinds of users thatare of interest to the advertisement sponsors are invited to differentchat rooms, perhaps inviting users who are considered to be premiumpotential customers to premium chat rooms while sending other users tochat rooms that are not as well supported by the advertisement sponsors.

FIG. 2B is fairly similar to that of FIG. 2A except that here the localmachine buffer 235 is collecting current vote indicators (Cvi's) ratherthan current focus indicators (CFi's). Vote indicators are generatedwhile the user is interacting with a specific chat room (or other onlinereal time forum) and is voting either explicitly or implicitly on thecontent found within that chat room. For example, the user may indicatepleasure or displeasure regarding other persons who have joined the chatroom and/or regarding the contributions that these other persons make tothe chat room. The explicitly or implicitly expressed vote may beaccompanied by exhibition of strong or weak emotional reaction (asindicated for example by biometric data). The vote detector 205 b picksup both explicit votes and implicit or inferred votes as well aspossible emotional feelings and strength of feelings underlying thosevotes. Sensors 203 b (which may be the same as sensors 203 of FIG. 2A)provide vote indicating signals to detector 205 b by way of signalsupplying paths 204 b (which may be the same as paths 204 of FIG. 2A).As mentioned above, inferred votes are those that can be acquired bygestures, vocal noises, or other body language of the user rather thanfrom explicit user indications. A Cvi records generator 236 converts theoutputs of the vote detector 205 b into corresponding current voteindicating and forum identifying packets. An example of the datastructure of a Cvi packet is shown in the magnification to the right.Each Cvi includes a user identification field 235 a. Additionally theremay be a machine identification field 235 b, a machine location field235 c, a time stamp field (in GMT format) 235 d. Moreover the type ofvote is indicated in field 235 e as being explicit or implicit. When avote is provided, it is associated with a specific item (e.g., chat roomand/or chat room participant and/or chat room proposal) that is beingvoted on. Different types of item identifiers may be used for thevoted-on items as is indicated by field 235 f. The voted on item may beidentified by URL alone of the associated chat room or other onlineforum (field 236 a) or by the combination of URL (or other unique pageor frame identifier plus keywords (field 236 b) or by URL in combinationwith a snapshot of some content (field 236 c) or by one or more keywords(e.g., including chat room name) given alone (field 236 d) or bycombination of one or more keywords plus a snapshot of certain content(field 236 e) or by system issued meta tag codes (236 f). Moreover thegiven list of focus and/or interest indicating types is non-limiting andas indicated by the “others” code field 236 g which allows for numerousother type of identifier codes including sending of emotional strengthindicators and/or original biometric data at the same time or a latertime after the vote indicator is stored into buffer 235. As in FIG. 2B,a data length field 235 g is provided for the identifier and the actualidentifier data is provided in field 235 h. Field 235 i holds the voteindicator. The vote indicator may vary for example in one embodiment itmay be a whole number in the range of 1 to 10. Alternatively, it may bea whole number in the range of −10 to +10. Alternatively, it may be areal number in a very large range spanning from negative to positive. Anadditional one or more fields (not shown) may be included for specifyingthe voter's likes or dislikes. Examples of such vote specifying data mayinclude: (a) I object to other user's behavior by this voting degree . .. ; (b) I am indicating that I consider the other user to be overlyargumentative to this voted degree . . . ; (c) I am indicating that Iconsider the other user to be of an agreeable personality or reputationor credibility to this voted degree . . . ; (d) I am indicating that Iconsider the other user's arguments to not be fact based to this votedon degree . . . ; (e) I am indicating that I consider the other user'scredentials to be valid (positive) or invalid (negative) to this votedon degree . . . ; (f) I am indicating that I wish to add to or detractfrom this other user's reputation by the following approving (positive)or disapproving (negative) amount . . . ; (g) I am indicating that Iwish to vote on the following pending room proposals (e.g., migrate theroom to a new node) as follows . . . ; and so on. Thus votes withvarious degrees of resolution and objectives may be registered with thesystem as desired. In one embodiment, the local client machine sortsvote indicating records (Cvi's) according to intensity of emotionassociated with the vote so that the Cvi's having relatively strongestemotional feelings (or corresponding biometric data) associated withthem will tend to be pulled (uploaded) by the cloud and processed by thecloud first.

Field 235J may contain a system recognized unique identification codefor specifying the chat room (or other online forum) whose contents orparticipants are being voted on. Not all chat rooms necessarily havesuch a system recognized unique identification code fitting into field235J (e.g., the topic node ID plus chat room number under that node)which is why URL or other identifications may be provided in fields 236a-236 f. Once again, as in the case of CFi's, a user password plusrandom session number may be used to form a digital signature thatcovers the Cvi content and this prevents vote spoofing. The entirevoting record (Cvi) may be covered by appropriate encryption whentransmitted over an untrusted or public channel.

In order to control resource bandwidth usage and allow for scaling, thecloud system 150 controls the rate at which Cvi records are pulled fromeach of the local machines 211′. Accordingly, Cvi pull requests 237 aare sent from cloud 150 to the Cvi records puller 237 of local machine211′. The Cvi records puller 237 responsively returns the requested typeof current vote indicator record(s) 237 b to the cloud. In oneembodiment, the Cvi records puller 237 routinely pings the cloud to letthe cloud know that the local user is still engaged with one or moresystem associated chat rooms and is thus probably casting implicit orexplicit votes regarding those chat rooms. In one embodiment, thesepings come in the form of Cvi buffer status packets that report on thestatus of buffer 235, its size and nature of data stored therein. If thepings stop for more than a predefined stretch of time, the cloud caninterpret that as the user having shut off his client machine ordisengaged the monitoring function and the cloud stops trying to pullCvi's from the Cvi buffer 235. Once again, the cloud may includestandard and premium service servers 151 d and 151 e which provides Cvipull requests at different rates depending on whether the user is usinga standard service or pays for a premium service. The pulled Cviresponses 237 b are forwarded to a chat room vote collecting server 151f. This server 151 f sorts through the various votes and allocates themto various users or chat room content as indicated by the content of thepulled Cvi. Contributors who receive consistent thumbs up (positivevotes) from other users in a given chat room generally have theircorresponding reputations incremented. Conversely chat room contributorswho have their contributions consistently voted down by other usersreceive negative scores and thus receive decreased reputations in theCpCCp “mine” records. Additionally, the content contributed by thevarious users may receive positive or negative votes and these votes arefurther accumulated. In one embodiment, the vote results are sent to atargeted advertisement server 151 g which uses the collected informationto better gauge how users are behaving relative to their viewing ofvarious topics at the current time. In response, the advertisers mayautomatically or manually adjust their advertisements strategy and/ortheir offered product mix accordingly.

A complex set of operations may occur in the cloud 150 between the timethat CFi's and/or CVi's are pulled and invitations come back or otherresponsive activities take place (e.g., automated bifurcation of a chatroom to thus separate warring participants). Just briefly and withreference to FIG. 1A, the AARMS services 150 a collect and initiallyprocess the pulled CFi's and Cvi's. The AARMS services 150 a may parsedata embedded in the CFi's and Cvi's and group the parsed data accordingto rules provided by the user's PEEP records (e.g., 199 of FIG. 1E). TheAARMS services 150 a may prioritize parsed and re-grouped CFi and Cvidata according to intensity of emotions associated with that data and/oraccording to other prioritizing criteria (e.g., whether the user ispremium service subscriber or not) and then hand off the prioritizeddata groups to one or more domain lookup (DLUX services 150 b) or otherservices (e.g., vote processing services) which then try to determinewhat specific topic or issue the respective content browsing or votinguser has on his or her mind when respectively focusing on nonn-chatcontent or voting on inn-chat content. Based on various lookup rules(e.g., 195 of FIG. 1C), the DLUX services 150 b make statistically-basedautomated determinations (automated best guesses) as to what is morelikely to be on the user's mind when showing focus on nonn-chat contentor voting on inn-chat content. The DLUX processed data is then forwardedto another service after best guesses are formulated as to what is morelikely to be on the user's mind. In the case where the system isexpected to download invitations to the user for chat rooms whosecurrent topic substantially matches the most likely current topics onthe user's mind, the DLUX processed data is then forwarded to theMatch-making services 150 c. The Match-making services 150 c use one orboth of recently pulled CFi's, Cvi's and domain/topic assignmentsprovided by the DLUX services 150 b and the user's CpCCp to findco-compatible chat rooms. Corresponding invitations are then generatedand sent to respective invitees. If a user votes negatively as to awhole of a chat room, that may be taken as feedback that thematch-making system did not match the user to the correct room.

Referring to FIG. 2C, invitations (Cciv's) to join a chat room arepushed from the cloud to targeted client machines like 211″. PushedCciv's are stored into circular or scrolling buffer 255. At the sametime a push flag is sent to an invitation records puller 267 in thelocal machine. Depending on how busy the local machine 211″ is withhigher priority tasks or not, the invitations puller 267 may elect toforward one or more of the recently received and buffered Cciv's (255)to a radar-like display generator 266 or not. In one embodiment, if theuser has set an activities monitoring switch to an OFF state, then nonew Cciv's are displayed through the radar generating and displayingsystem 266-265. In one embodiment, the invitation records puller 267includes an invitations and suggestions rater and sorter that sortsinvitations and suggestions according to one or more criteria includinghow on-topic the received invitations/suggestions appear to be relativeto a topic that the user appears to currently have on his or her mind,according to how aged the invitations and suggestions are relative towhen corresponding CFi data was sent out and/or according to how quicklyacceptance by the user is needed for the receivedinvitations/suggestions before they become stale (e.g., before a chatroom closes because its maximum population quota has been reached). Theinvitations and suggestions rater and sorter (267) then assignsrespective stronger and weaker recommendation ratings to the sortedinvitations (e.g., to chat rooms) and suggestions (to other on-topiccontent). The radar display system may include display format controlmodules 265 by way of which the local user and/or a supervising systemcontrols the format and/or other attributes of her on-screen invitationsdisplaying radar. In one embodiment (see briefly FIG. 3B), the displayformat control module 265 may include display format controls forpresenting the user with recommendations for additional on-topic contentas a supplement to, or independent of invitations presented to the userthat link to on-topic chat rooms. In one embodiment, the displayed radarmay take the form shown in FIG. 1D. In an alternate embodiment, thedisplayed radar may take the linear banner form 315 shown in FIG. 3A. Inyet another alternate embodiment, the displayed radar may be of hybridform between the two where plural U-shaped flows ofinvitation-representing bubbles converge at a location where the closedends of the U-shapes meet or almost meet and where one symmetrical halfof each U-shaped flow represents incoming invitations that moving closerinto agreement with the user's current focus while the other half ofeach U-shaped flow represents diverging invitations whose correspondingchat rooms appear to be currently moving apart from correlation with theuser's current focus. If new Cciv's are displayed through the radargenerating and displaying system 266-265, then the user may elect toignore them or accept one or more or more of the invitations. Invitationacceptance and/or rejection/ignore activities by the local user aremonitored by a local invitation acceptance control unit 268. Unit 268may keep track of how long it takes for the user to spot an invitation,explore its details and then optionally accept it or instead expresslyreject it or choose to ignore it. Unit 268 may also keep track of howlong the local user stays in each chat room and how aggressively theuser participates in the ongoing chat transactions. The correspondinginvitation handling information 257 b may be sent back to the cloud 150for further processing for example by standard or premium servicesservers (virtual servers or real servers) 151 h and 151 i. If thereturned response 257 b included an acceptance, a corresponding chatroom entry service 151 j is activated for opening a chat room window orframe on the user's machine 211″. In one embodiment, service 151 jcauses a download of executable instructions (e.g., a java script) to besent to the client machine (e.g., by way of a supervising AARMS) whichexecutable instruction signals, when received and accepted, cause thechat room window or frame to open on the user's screen. Additionally,invitation handling information 257 b may be forwarded to a targetedadvertisement service 151 k that process the user's invitationacceptance and/or rejection/ignore activities and thereby automaticallydetermines what advertisements may be optimally targeted to the givenuser and at what frequency and/or what product mix may be optimallyadvertised to the user. Similar to the cases of FIGS. 2A and 2B, thestandard and premium services/servers 151 h-151 i of FIG. 2C providedifferent rates of pushed out invitations and/or forced advertisementsdepending on what compensation if any is provided by the user.

An example of a possible invitation record data structure is shown at255 a-255 k. Similar to the cases of FIGS. 2A and 2B, the top entries255 a-255 d respectively provide user ID data, machine ID data, machinelocation data, and invitation time stamping data (time the invitation isissued). Entry 255 e denotes the type of invitation. There can bedifferent kinds including for example high priority and low priorityones, invitations to relatively public chat rooms and invitations torelatively closed rooms (or to other online and/or real time forums);rooms logged under specific hierarchy nodes of the system (see FIG. 4B)and those that are not. The local radar generating and displaying system266-265 may optionally and responsively display the different kinds ofinvitations differently (e.g., with flashing red border for highpriority ones, etc.) if the user indicates a desire for such intrusivealerts by user settings made in the radar display control module 265.

The focus/domain/topic identifier field 255 f may denote which one ormore focal areas of the user's screen content and/or which domain and/ortopic/subtopic the incoming invitation (Cciv 257 a) is directed to. Aswas the case with FIGS. 2A and 2B, there can be many different ways toprovide this information. Included among the possibilities are those ofentries 256 a-256 f whose counterparts have been discussed above. In thecase of keywords and/or meta-tags, the corresponding content areas (ifstill on screen) may become highlighted in yellow or by some other meanswhen the user floats an on-screen cursor (via mouse and/or eyeballmovement) over the invitation. The content pinpointing information ofentry types such as 256 b, 256 c, 256 e, 256 f, etc. may be used fordetermining what on-screen content should be highlighted or otherwiseflagged to show relationship to the user. In one embodiment, thefocus/domain/topic identifier field 255 f or another field added intoCciv#1, stores and provides information about the chat room subjectmatter that would help the user decide whether or not to accept theinvitation. This type of subject matter data may include the predefineddomain/topic node names and node descriptions, and/or the chat room nameand description assigned by the chat room members, or associatedinterest domain and topic coefficients as well as their userco-compatibility coefficients. In one embodiment, the focus/domain/topicidentifier field 255 f or another field added into Cciv#1, stores andprovides reminder information that reminds the user (by brieflyprojecting it or highlighting it) what content caused the invitation tobe sent. In one embodiment, this additional information is displayed inthe “informational balloon” such as 117 b of FIG. 1D.

As was the case with FIGS. 2A and 2B, entry 255 g indicates the lengthof the invitation focus/topic identifier, entry 255 h provides thefocus/topic identifier data. Entry 255 i indicates a degree oftopic/subtopic match between the local user and the chat room to whichthe Cciv is providing an invitation. Not all users will be found to beprobably focusing on exactly the same topic/subtopic/etc. of the givenchat room. However, the invitation generating services/servers 151 h-151i may nonetheless have elected to send an invitation to the user with anindication 255 i of how far apart the user is from the chat roomtopic/subtopic/etc. hierarchy. The closeness of match indication 255 imay be used to determined how the invitation is displayed on the user'sinvitation radar (e.g., that of FIG. 1D or FIG. 3A).

Similarly, entry 255J indicates the degree of chat co-compatibilitybetween the user and the cumulative attributes of the invited-to chatroom. Not all users will be found to be exactly co-compatible withexisting or to-be-formed chat rooms. However, the invitation generatingservices/servers 151 h-151 i may nonetheless have elected to send aninvitation to the user with an indication 255J of how far apart theuser's preferences are for an ideal chat room as opposed to thecumulative attributes (e.g., average chat partner education, age, etc.)of the actual chat room for which the invitation is directed. The degreeof co-compatibility indication 255J may be used to determine how theinvitation is displayed on the user's invitation radar (e.g., that ofFIG. 1D or FIG. 3A). In one embodiment, different aspects ofco-compatibility may be separately graded and indicated to the user,namely, degree of personality co-compatibility, degree of topicco-compatibility and degree of topic proficiency co-compatibility. Entry255 k provides a system recognized unique room ID so that if and whenthe user accepts the invitation, unit 268 can return a responseindicating which room the invitation is being accepted for. Entry 255Lprovides a password covered digital signature from the invitationgenerating services/servers 151 h-151 i so that rogue servers cannoteasily spoof at being invitation servers.

FIG. 3A is a plan view of an exemplary user screen or user window 300provided in accordance with the disclosure on a user's client computermachine (e.g., 115 of FIG. 1A). The displayed content of screen 300 mayprovide one or more conventional control menus such as 311 forcontrolling file retrieval, controlling file saving, for editing filecontent and so forth. (Reference numbers like 311 do not appear on thescreen and are embraced in hyphens, e.g., -311- to indicate this.)Additionally, the display 300 may include at least oneinterest-monitoring control menu such as that illustrated at 312. Theinterest-monitoring control menu 312 may include a current monitoringstatus (e.g., “=ON”) which indicates whether benign spying is ongoingwithin a corresponding window or whether such spying activity iscurrently turned off. The user may toggle the state of the flag betweenon and off as desired for example by clicking with the mouse when cursor335 is over the flag area 312. In one embodiment, the “=ON” flag slowlyflashes as a dim orange graphic to remind the user that monitoring iscurrently turned on.

By way of more specificity, user editing and/or saving functions enabledby the file control menus 311 may include menu options for performinginvitation system related actions such as changing passwords, updatingaccount subscription levels, entering or changing demographicinformation (e.g., user indicates he moved to a new address, his incomelevel has changed, etc.), or entering preference data change requests(e.g., user indicates he no longer wants to chat with people under 25years old). These invitation system related menu options under 311(specific options not individually shown) would be saved locally in oneembodiment and then uploaded to a cloud server when bandwidthopportunistically becomes available for such uploads of account changingdata. The altered account settings would then be reflected back from thein-cloud server to multiple client computers of the user. Thus universalchanges to account settings can be made from any user client machine. Inone embodiment, an email is sent to a user selected email accountinforming of the account setting changes. In one embodiment, menuoptions for modifying account settings and/or profile preferences areprovided as task orientated and context triggered options rather than asuniversal file orientated options. For example, a menu option forupdating a list of other users whom the client likes or dislikes may beautomatically provided in an instant messenger window under a simple“buddy list” menu entry. When the user adds, deletes or changes thelocal list, the changes are saved and uploaded to the cloud so as tobecome universal changes under that client's account settings.

In a menu bar area directly below menu bars 311 and 312, a chatopportunities banner or marquee 315 may be scrolling through. In analternate embodiments, the opportunities banner 315 may appear along anyone or more of a bottom, left or right side edge of the screen or as apop-out menu bar that pops out only when the user moves cursor 335 tosuch an edge. The items in the illustrated banner area 315 may scrollfor example from right to left to indicate chronological ordering, whereitems on the left side of the screen (e.g., shrinking bubbles 315 z)disappear after crossing beyond the edge and new items (e.g., enlargingbubbles 315 e) appear to emerge from the right edge of the screen. In analternate embodiment, items (e.g., 315 c) that are drifting towardsand/or are positioned near the middle of the banner area represent themost important (most highly scored in terms of topic and chatco-compatibility) among the most recent invitations while less importantand/or older items (e.g., 315 a, 315 z) are displayed as reduced insize, shrinking and moving off the end of the banner, this indicatingthey no longer correspond to the user's current area of focus in termsof content and/or topic of interest. In yet another embodiment(mentioned above) plural U-shaped-like flows (with possible shortcircuiting tributary flows between symmetrical halves of the U-shapes)may converge from edges of the screen or a window towards a central areasuch as 315 c. The scrolling-in-and-through-and-out opportunity icons oritems 315 z, 315 a-315 d, 315 e represent respective invitations intodifferent chat rooms, otherwise referred to here as chat opportunities.Each invitational icon (e.g. 315 a) may have respective internal text, abackground color and/or foreground graphics at its center for indicatingthe topic or domain to which it applies and/or the urgency or importanceof the invitation. In one embodiment (although not all shown), theopportunity icons transform from incoming opportunity bubbles (315 e)into animated cartoon or other faces which grow in size, agitationand/or opaqueness as they drift towards the banner area representinggreatest importance, current relevancy or urgency of the invitation andthen the animating faces (e.g., talking heads not shown) drift outwardlyagain and shrink back into aged bubbles (315 z) that finally drift offscreen.

If the user hovers a mouse cursor (e.g. 316) over one of the slowlyscrolling-by chat opportunities (e.g., 315 a) for a predefined length oftime (dwell time, challenge time) or clicks on it, then a correspondingand more detailed informational window opens up (e.g., and informationalballoon, not shown) which provides the user with more detailedinformation about the domain and topic of the given chat opportunity(e.g., 315 a). In one embodiment, the more detailed informational windowappears as a semi-transparent window hovering over one of the alreadyopen content windows such as 317. This indicates that the challengedchat opportunity (e.g., 315 a) corresponds to content found in window317. In one embodiment, one or more keywords related to the challengedchat opportunity (e.g., 315 a) glow or otherwise become prominent toindicate they are especially related to the currently challenged chatopportunity. In the illustrated examples open window 317 provides aframe of content obtained from a remote or local URL (universal resourcelocater) denoted as www.URL.com/A4. If the cursorn-challenged chatopportunity 315 a corresponds to specific content within open window317, then in an alternate embodiment, the border of the correspondingwindow 317 glows or changes color or flashes and/or specific contentwithin that window 317 becomes enlarged and/or bolded to therebyindicate the correlation between that specific content and thechallenged opportunity. Additionally or alternatively certain keywordsor images within open window 317 may become temporarily underlinedand/or highlighted in a different color as the user moves his cursormouse 316 challengingly over the scrolling-by and interrelated chatopportunity (e.g., 315 a). In each of these cases, the temporarilyhighlighted window and/or temporarily highlighted content within one ormore of the open windows (e.g., 317, 318, etc.) indicates to the userhow the chat opportunity (e.g. 315 a) corresponds to those alreadyopened content frames or windows on his display 300 and/or to contentwithin those one or more windows. In one embodiment, the vise versa isalso true; namely, if a user right clicks on or otherwise highlightscontent (and optionally picks a show invitations option), thecorresponding invitations in the invitations display area 315 glow orotherwise make their identity known to the user.

If instead of hovering or once clicking, the user double left clicks hismouse 316 over the available chat opportunity (e.g. 315 a) then a newchat room window such as 316 a opens up along an alternate side edge(e.g., left) of the screen. Of course, in the same or other embodiments,the user can use other pointing devices and/or hand gestures and/orvoice commands to effect the opening of a chat room window based on anoffered chat opportunity. The newly opened frame 316 a may include roomidentification indicia (e.g., “Room A0”) as well as an interior frameshowing a transcript of the latest conversations occurring insubstantially real time within that room (A0). For example, it is seenat 316 d that Sam and Sally are conversing in essentially real time inroom B3 about something in yesterday's newspaper editorial. The localuser can then quickly review the content of what is currently occurringin the newly displayed rooms (A0 and/or B3) and decide for himselfwhether to keep that chat room window open on his screen or to close itdown. If the user quickly shuts down the just-opened chat room window(e.g., A0), then this event is reported by the local activities monitor(LAMS 105 x) to the remote match-making and invitations-generatingsystem (MM-IGS) and appropriate services within the remote cloud takethat event as a negative vote against the offered chat room invitation315 a, this perhaps indicating to the remote matching service that thematch-making part of the service guessed wrong as to what topic the userwas thinking about and was interested in chatting about. On the otherhand, if the user leaves open the just-opened chat room(s) (e.g., A0,B3) for relatively long times and/or begins to actively scroll throughthe transcript and/or begins to contribute to transcript content (316 d)in one or more of them, then these respective local activities areinterpreted as affirming to the remote cloud, at respective progressivelevels of increased confidence that the remote matching service hadguessed correctly as to the user's interest in the topic of thisparticular chat room and as to the user's co-compatibility with thisparticular chat room. Room scrolling arrows such as down pointing 316 fand the up pointing one below 316 e may be used to review newer or olderopened rooms. Both negative and affirmative responses to challenged ornewly opened chat rooms (or challenged older and re-reviewed rooms) areused by the remote matching service as feedback information for activelylearning about the user's preferences and to adaptively adjusting theuser's preference records (e.g. DsCCp's) accordingly. Additionally,biometric data collected from the user at the time he challenges orfirst opens and exams a chat room can be used by the remote matchingservice as feedback information for actively learning about the user'spreferences.

In one embodiment, after a given chat room transcript window (e.g. 316b) has been open for a relatively long predetermined time, a newscrolling side band such as 316 c appears adjacent to that transcriptwindow 316 b. The icons of scrolling band 316 c represent chatopportunity offers made from inside of the already opened chat room 316b. In this case the chat opportunities 316 c are those that are moreclosely related to the content inside of transcript 316 b and, as in thecase of the main screen scrolling banner 315, the user may mouse overand click challenge (or otherwise challenge) one of the icons inscrolling banner 316 c to learn more details about its content.Alternatively, if the user is annoyed by the presence of in-roomopportunity banner 316 c, the user may click on a menu-provided controlwhich removes scrolling banner 316 c from window from 316 b. In oneembodiment, the in-room opportunity banner 316 c is not displayed untilthe system detects (from biometric data) that the user is showing fadinginterest in the currently open chat room 316 b, at which point theinn-chat invites banner 316 c automatically opens to show potentiallybetter opportunities. Additionally in one embodiment, the user mayexplicitly request opening of the inn-chat invites banner 316 c byactivating an appropriate menu option. Each of these various useractions (e.g., close inn-chat invites banner 316 c, explicitly opensame, etc.) may be flagged by the LAMS 105 x to the remote matchingservice 150 c to indicate that the scrolling banner was respectivelyannoying in one case to the user and that user prefers not to have itoffered at least in the same context or that the scrolling banner wasrespectively desired by the user and that user prefers to have itoffered at least in the same context. The remote match-making andinvitations-generating system (MM-IGS) takes note of this behavior,optionally changes in-system knowledge-base rules stored for the user,and adapts accordingly. One of the adaptations may be to increase thelength of time before a chat-room internal banner such as 316 c isoffered to the user. Another possible adaptive behavior is to ask theuser whether he no longer wants to be offered such in chat roominvitations to interrelated other chat rooms either for the specifictopic area or domain or for all domains. Alternatively, the user mayelect to shrink and hide the side banner 316 c just along a side edge ofchat window 316 b and to have it responsively pop out when he mousesover to that extreme side. Just as inn-chat room window banners like 316c can be hidden from the user at the user's request, the main on-screeninvitation banner 315 can also be temporarily hidden from the user'sview when the user no longer wants to see it and it can be brought backwhen the user is ready to see it again. In one embodiment, when the userhides his banner 315, a message is automatically uploaded to the MM-IGSto temporarily halt the match-making and invitations-generating servicesfor this user. In one embodiment, when main banner 315 is minimized forhiding, it shrinks into a small blinking dot at the top or side edge ofthe screen 300. The user can double click on this blinking dot toreinstate the full and moving scroll banner 315. At that point, thelocal client machine automatically signals the MM-IGS to resume thetemporarily halt match-making and invitations-generating services forthis user. Aside from mouse actions for invoking shrinkage-and-hide orexpansion-and-resumption of invitations-representing banners such as 315and 316 c, in one embodiment, the user can use keyboard shortcuts, voicecommands and/or hand or other gestures that his local machine has beentrained to recognize as commands for the desired banner shrink andexpand operations. Accordingly, the user may reclaim his screen spacefor primary functions at times of the user's choosing and de-collapsethe minimized banner at other times. Workload for the remotematch-making services may be automatically reduced at times when theuser cannot see his invitations-providing banner. However, CFi's maycontinue to be uploaded to the cloud for purpose of learning about theuser's current areas of interest (provided interest_monitoring 312 isleft turned on). The software and/or hardware for causing the user'slocal machine (e.g., 115) and the in-cloud remote services 150 toautomatically carry out respective ones of these various actions are ofcourse provided in respective hardware and/or software resourcesprovided in each as appropriate, where this will be understood byskilled artisans in the relevant useful arts after reading thisdisclosure.

In addition to providing a scrolling-through display of a handful ofcurrent chat opportunities 315 a-315 d, each opportunities offeringbanner such as 315, 316 c may include chronological “more” arrows suchas 316 e and 315 f at one or both of their extreme ends. An old side“more” arrow such as 316 e allows the user to recall and enlarge olderitems (e.g., 315 z) that had shrunk and/or passed out of sight beyondthe left edge. (In one embodiment, arrow 316 e points to the rightrather than left.) A newer side “more” arrow such as 315 f allows theuser to indicate to the opportunity displaying services (local and/orremote) that the user currently wants the banner 315 to advance morerapidly so that the user is provided with a greater number of newinvitations (315 e) per unit of time. There can also be a “less” arrowsuch as 315 g whereby the user flags that he currently wants the banner315 to advance less rapidly or for new invitations (315 e) to stream inmore slowly. In one embodiment, if the user is not subscribed as apremium user, pressing the newer side “more” arrow such as 315 f willautomatically bring up an advertisement message such as one telling theuser that he or she must subscribe to a premium service in order to beable to use the “more newer” invitations feature 315 f.

Icons within the scrolling banner 315 may be differently sized (e.g.,proportionally sized) to indicate the degree of topic matching and/orchat personality co-compatibility for chat rooms which the remoteservice has found. Or the degree may be explicitly indicated as anattached number or meter scale. For example, illustrated chatopportunity 315 c may be relatively larger sized and/or differentlycolored on its border to indicate that this is probably a chatopportunity of more intense interest to the given user at this time thanothers of the chat opportunities 315 a-315 b, 315 d scrolling along themarquee 315. The displayed chat opportunities 315 a-315 d may apply to asame chat topic or to different chat topics and/or different domains.The respective chat topics may be indicated by bubble-internal text orbubble-internal graphics and/or by color coding of the surroundingborder of each one of radar-like blips 315 z, 315 a-315 d, 315 e. In oneembodiment, each user may specify through a local display control (e.g.265 of FIG. 2C) the various ways in which the chat opportunity bannerse.g. 315, 316 c are to indicate their respective chat topics as well ascloseness of co-compatibility and topic sameness. As mentioned above, inone embodiment, user reactions to items inside the invitationsdisplaying banner or radar scope are not reported by uploaded CFi's.Additionally, if the user is detected to be busy focusing upon acurrently open chat room, then portions of the benign spyware directedto reporting on out-ofn-chat activities (e.g., CFi generation) may betemporarily put into hibernate mode. Also, the local client machine maytemporarily stop pinging the cloud for new invitations (invitationsbased on out-ofn-chat content) while the user is detected as beingcurrently occupied with one or more chat rooms.

FIG. 3A also shows that various mechanisms may be present on the user'sdisplay 300 for indicating focus of attention on different kinds ofcontent providers and on different topics. For example the open browserwindow 317 contains an HTML-coded (or XML-coded) web article related toa topic named, A. The local activities monitor (LAMS 105 x of FIG. 1A)may detect that the user's eyeballs (more specifically, his pupils) arepointed at and thus presumed to be concentrating on certain words orsubareas within window 317. The focused upon words or snapshots of thefocused upon areas may be included in the CFi packets sent to the remoteserver in relation to window 317. Alternatively or additionally, unseenmeta-tags 317 a that are buried in the source code (e.g., HTML, XML) ofthose focused upon content areas may be included in the CFi packets sentto the remote server.

Meta-tags 317 a that are generally hidden form the user's view (but maybe seen in most instances by viewing the underlying mark-up code, i.e.HTML, XML) can come in a variety of types. Examples of possible codes ortags include search-engine assisting/attention-getting codes, popularityengine tag or subject-matter categorizing codes, and hierarchynavigation codes. Search-engine assisting/attention-getting meta-codesor meta-tags can be of the type that web content authors embed in theirweb source code to direct search engine searches or social networkingservices to the given content (or to draw attention of the same to thegiven page) based on search words (e.g., keywords) that a lay user isexpected to enter into a search engine service (e.g., Google™, Yahoo™,etc.).

Popularity engine tag codes or “tags” appear in separate popularityengine web pages adjacent to an identification of the URL that is beingpopularity-wise rated by users of the popularity-based rating engine.Authors of source content may sometimes embed in their displayed webpage, redirectors (e.g., Digg-It!) that when clicked, link the user to acorresponding user popularity rating engine (e.g., social networkreputation rankers such as Delicious™ (a.k.a. Del.icio.us™) Reddit™,Digg™, Stumbleupon™) where at the engine site, popularity engine tagcodes (“tags”) or subject-matter categorizing codes (e.g., photos,humor, movies, books, etc.) appear for purpose of categorizing theto-be-rated web page according to categorizing tags. The subject-mattercategorizing codes or tags may be used alone or in combination to hintat a corresponding topic. More specifically, if a user of the MM-IGSsystem (FIG. 4A) is focused upon content at a first URL (URL-#1), in oneembodiment, the MM-IGS system automatically looks up the tags for thatURL-#1 at the web sites of one or more social network reputation rankers(e.g., Delicious™, Reddit™, Digg™, Stumbleupon™, etc.) and collects thetags under appropriate tag-supplier headings (e.g., Reddit™-tags,Digg™-tags, etc.). Then it automatically identifies the most often usedof these subject-matter categorizing tags and stores them in storagearea 455 b as respective, most-often associated Reddit™-tags,Digg™-tags, etc. Most-often-associated popularity tags can come in twoflavors: (a) most often found to be associated with the URL's providedin the user CFi's of all users touching on the node (e.g., 450) taken inwhole; and (b) most often found to be associated with the URL's providedin the user CFi's of users participating in a given chat room runningunder the node (e.g., 450). These subject-matter categorizing tags (asstored and organized in region 455 b) may be used alone or by alsoautomatically referencing what the associated popularity rating engine(e.g., Delicious™) says (in an indexed database of the popularity ratingengine) about the topic of the given URL to automatically determine whatthe probable topic is of one or more URL's found in a given user's CFiuploads, and to identify the best matching topic nodes within the systemhierarchy tree based on the one or more URL's found in a given user'sCFi uploads.

Hierarchy navigation meta-codes are special ones developed herein foruse with domain/topic/etc. hierarchy trees such as shown in FIG. 4B.Basically, the system operator of one or more match-making data centers(e.g., 410, 420 of FIG. 4A) create a Dewey-Decimal like system thatassigns whole integer values for navigating to main topic domains andsubdecimated values to topics and subtopics so that a hierarchynavigation meta-code of the form, for example, 078.456,123 points to adomain node that has been pre-assigned the 078 number as its rootaddress in the hierarchy tree (e.g., of FIG. 4B); and then it furtherpoints to a child of that domain node that has been pre-assigned the 456number as its address under the 078 domain; and then it further pointsto a grandchild of that domain node that has been pre-assigned the 123number as its address behind the 456 topic node. In FIG. 4B suchhierarchy navigation meta-codes are denoted as navMeta-Tag codes (e.g.,item 405 in FIG. 4B). Although a Dewey-Decimal like system is onepossible way of organizing the hierarchy navigation meta-codes, thepresent disclosure is not to be construed as being limited to that oneoption. Alphabetic letters and/or other characters beyond just numberscan be used and different characters such as dot (.), forward slash (/),back slash (\), colon (:) for example may be reserved to function asnavigation delimiters. Alternatively, a respective unique list ofspecial meta-tags may be pre-assigned to each node in the hierarchy treeand used to navigate to that node. Moreover, special aliases may bedevised to jump directly to a popular node or user favored within thehierarchy tree rather than always navigating by starting at the tree'sroot node (402). In one embodiment, the meta-tags includescope-indicating pointers or indicators that indicate the boundaries ofthe content to which they are directed, for example a meta-tag whosescope-indicating attribute indicates the meta-tag applies only to thecurrent sentence, or paragraph, or web page or web frame and so on. (Todo this may require use of specialized meta-tags that can violategeneral HTML industry validation rules that dictate where in an HTMLdocument, meta-tags can be placed—generally only in header sections.Accordingly, custom content that is meant to be hidden and yet assignattributes to specific sentences or paragraphs, etc., may have to beinserted as a masquerading part of a valid tag that points to theaffected sentence, etc. or to be included as hidden comment code in theHTML source code where the application code of the present systemnonetheless reads the comment code and acts on special comment stringsembedded in the comment code.) In one embodiment, every node in thehierarchy tree (FIG. 4B) is assigned a respective unique node ID tag(e.g., 450 a for node 450) that uniquely identifies the nodeirrespective of the node's current placement in the tree (or the node'scurrent placement in a topic space such as that of FIG. 6). The uniquenode ID tag may be generated for example as a concatenation of the dateand time (e.g., down to the millisecond) and place (e.g., which datacenter, which storage unit in the center, etc.) of when and where thenode was first created and optionally one or more random numbers furtherembedded in the concatenation. An alternate approach is to use a GUID(Globally Unique Identifier) provided by a single source within thesystem, where the GUID is a computer generated series of letters andnumbers used to uniquely identify records that need to be shared acrossmultiple database servers. In one embodiment, the unique node ID tag 450has appended to it, a unique data center code and polar coordinatesindicating where in a corresponding one or more polar topic spaces (seeFIG. 6) the node is currently positioned. The polar coordinates are notpart of the unique node ID because those coordinates can and usually dochange when the node migrates to a new location in the hierarchy treeand/or to a new location in topic space. When a node is mirrored into adifferent data center, its unique node ID tag (e.g., 450 a for node 450)does not change. In this way, the node's unique node ID tag (e.g., 450 afor node 450) may be used to identify the node irrespective of it'splacement in the hierarchy tree and/or it's placement in an identifiedtopic space and/or its replication into different data centers and/orits change of name over time. (The usefulness of this feature willbecome apparent later.)

Window 318 shows the local user as watching a web video (having animatedimages and corresponding audio) relating to topic B. This viewing stateof the user may be assumed for example in response to automateddetection that the current audio output of the client machine is thatgenerated from window 318. The amount of time spent watching the movingimage B and/or fiddling with the volume control may indicate the amountof interest that the user has in that specific topic. Window 319 showsthe local user as listening to a podcast. Once again, that state ofaffairs may be assumed for example in response to automated detectionthat the current audio output of the client machine is that generatedfrom window 319. The current volume setting and/or fiddling with thevolume control may indicate the amount of interest. Additionally, theuser's local camera (116) may spot him as tilting his head back andlooking away from the screen while concentrating on the audio content.Meta-tag data may be buried in the digitized audio and/or video (e.g.,in horizontal or vertical blanking intervals) to indicate the likelytopic of interest and this meta-tag data may be uploaded to the cloud aspart of a CFi. Biometrically sensed activities may indicate intensity ofuser interest in the topic being covered at the time by the streamingaudio data.

On-screen content may alternatively or additionally include non-web(non-network originated) material such as a locally stored wordprocessing document 320 that the user is working on, where region 320 dmay be a section of the document that the user has been currentlyediting (and for which a recent edits history is maintained andoptionally uploaded to the match-making and invitations-generatingsystem (MM-IGS)). In the illustrated example, window 320 has a file-namearea 320 a indicating a file named, Fifth_Grade_Science.doc. In oneembodiment, this information is confidentially uploaded to the MM-IGS incombination with other data (e.g., the recent edits history) foranalysis and topic determination. Word processing documents such as 320often have their data structured differently from that of an HTML-codedweb page. Nonetheless, they may have sections that are likely to betopic headings or introductory summaries (320 b) of the material belowthem and thus indicative of the topic the writer is thinking about whenworking on the document as a whole or on a particularly headnotedsection. In this case the writer is thinking about doing a fifth gradescience project that involves experimenting with different tasting areasof the human tongue. The file name, Fifth_Grade_Science.doc, gives thematch-making service (in the MM-IGS) a first clue. Dominant words orphrases 320 c repeated throughout the current version of the documentmay also be uploaded to the MM-IGS to give the match-making service yetmore clues. A recent set of repeated edits made in section 320 d (asindicated by the edits history) may give the MM-IGS an indication thatthe user is having difficulty with this particular section 320 d. Giventhe age of the logged-in user and the clues provided by window 320, andher personal preferences (CpCCp and DsCCp('s)), the in-cloud MM-IGS maydetermine that the user likely wants to chat with other fifth graders(in somewhat remote geographic locations rather than in her local schooldistrict where she is competing with schoolmates) who are doing scienceprojects on tongue tasting. Students can exchange useful insights withsimilarly situated other students and thus they can come to find theschool work much more interesting if they have people to share theirexperiences with. For example, noncompeting students can share in acommon chat room, some of the resource materials they used to preparetheir science projects. In one embodiment, the science project chat roommay be monitored and moderated by a nongrading teacher who hasvolunteered to help keep the students on track without interfering withtheir spontaneity or enjoyment of the chat room.

Alternatively, the reason that the local user has been making repeatededits for a relatively long recent time in document area 320 d isbecause she is having trouble with a grammar issue, or with a sentencestructure issue, etc. In other words, she is having trouble with thewriting process itself rather than with the overlying subject matter(e.g., the science experiment project). There will be cases where thematch-making service (e.g., MM-IGS) will not be able to determine to anyreasonable level of disambiguaty whether the user is thinking about thewriting process or another issue. In such a case the flow of incominginvitations may be in the form of multiple incoming streams (e.g., likethe U-shaped flows mentioned above) and the user picks (if at all) thestream that appears closets to what she is currently thinking about.This pick among different probable topics is fed back to thematch-making system and the system then begins to send more invitationsin line with the picked topic, while in some cases, continuing to offeroccasional invitations for the other possible topics. (Because once aproblem with writing style is resolved, the user may continue to editthe same area 320 d while this time switching the topic of interest—inthe user's mind—to the overlying subject matter; e.g., the scienceproject.)

The types of possible local files (e.g., 320) that the local user may beworking on are almost endless, and need not be limited to wordprocessing documents. For example, two or more computer programmers indifferent locations may be working on a similar coding problem (e.g.,for example how does a particular public library function behave whengiven certain esoteric input parameters?) and they may want to sharetheir frustrations or insights with one another. The match-making systemcan automatically find such otherwise isolated persons and pair them upfor chatting with each other in real time. For example, the local clientmachine of each computer program writer may detect the local coder'sfrustration or uncertainty over a certain library function based onbiometric indicators collected from the writer. In response, the localclient machine software may automatically suggest an uploading of someof the content to the match-making service for purpose of linking thelocal user into a currently ongoing chat room that is discussing thissame coding problem or to another user of predefined proficiency who iscurrently focusing on this same coding issue. (Since part of the codethe local writer is working on may be confidential, the local software105 is configured to automatically detect that the file content isconfidential and to responsively request user permission to upload ahighlighted portion with a warning that the user should verify thehighlighted portion does not contain confidential material. Thus, in thecase where some of the focused-on material may be confidential, thelocal software asks for permission and provides a warning beforeuploading the presumably non-confidential subsections of the focused-onmaterial to the MM-IGS. (Even if the material is not confidential, insome embodiments the MM-IGS does not show the uploaded, focused-onmaterial to the other users and thus the material is not in danger ofbeing compromised. As mentioned earlier, in some embodiments the contentof the uploaded CFi's is covered by an appropriate encryption process sothat other people on the public network (e.g., 430) cannot easily snoopand see what system users are working on.)

Students working on similar school projects and computer programmersworking on similar coding problems are just a few examples of the kindsof people that may find each other via the match-making service andcollaborate. Lawyers working on similar legal problems may use thesystem to find each other when their focus is on a same legal issue (forexample, what is the definition of a “trade secret” in the State ofCalifornia?) Research scientists who are reviewing the samenon-confidential journal articles may use the system to find each other.Ditto for at home cooks who are reviewing the same recipe, book readerswho are currently reading the book(s) of a specific author, and so on.The list can be endless while the benefits of match-making betweenotherwise isolated local users can also be endless. Each kind offocused-on local file may have its own unique style (e.g., definingwhere the headings are positioned, where the abstract or summary ispositioned, where relevant footnotes or endnotes are positioned etc.)and the match-making service may be configured to recognize and workwith different kinds of common styles.

Window 330 shows the local user as using a popular search service (e.g.,in a prespecified recent stretch of time) for performing an onlinesearch for certain keywords and receiving responsive results. The URLaddress bar 330 a may be used to identify the specific engine and thusinfer the data structure of the displayed web page including where thesearch keywords are located (330 b) and where the search results arelocated (330 c). The local client machine keeps track of when the userhas last used an available search engine and what content was focusedupon shortly before and/or after the search. For example, if the userwas editing in section 320 d of window 320 less than a few minutes agoand now the user has entered the search keywords, “theory of taste” intokeywords input area 330 b of the search engine 330 a, the match-makingservice can infer from this that the topic of interest is not oneinvolving a writing style issue but rather one narrowed down to a topicconcerning theories for how the sensation of taste occurs. Soon afterthe search engine returns results in area 330 c, the user may move hismouse cursor (335) to dwell over and/or highlight and/or hyperlink tospecific ones of the results in area 330 c, this indicating differingdegrees of increased interest in those specific results. Thisinformation may be forwarded via the CFI's to the remote matchingservice 150 c for automated analysis and determination of what subtopicunder the theory-of-taste node is currently on the user's mind. Theamount of time the user spends in dwelling over or inside specific onesof the search engine results 330 c may indicate to the match-makingservice what the user's current level of interest is in that subtopic orwhether the user is having trouble with the search results and wants todiscuss the difficulty with like situated other users. Biometric dataobtained from the user at this time can help the match-making service toautomatically decide whether the user is probably feeling frustrationover the results or a heightened interest of a positive kind. Thematch-making service may then make recommendations (by providingcorresponding invitations) one way or another based on the inferredemotional states of the user.

With regard to sensing frustrations or other emotionally chargedreactions of local user to something happening or that recently happenedon his or her local machine (e.g., search results that do not meet theuser's expectation, or chat room developments that upset the user), partof the biometric processing software can be specially directed todetecting expressions of exceptional frustration or other exceptionalemotionally charged reactions exceeding the user's norm. The user mayverbally express profanities or the like while staring at the computerscreen generally or at a particular area on the computer screen for aprolonged period (e.g., more than a second) and/or the user may start toengage in “flaming” activities where the user is projecting impolitecontent to other users in a chat room or other forum, even if notactually transmitting that flaming content to the others. The specialsoftware may use voice recognition modules to automatically detect theunusual use of objectionable language by the user and/or change in voicetonality, change in stress levels or in other vocal system parameters(e.g., including changed breathing patterns) to classify this behavior,if it is markedly unusual for this user, as being an indication ofexceptional frustration at or other exceptional emotionally chargedreaction to something going on in the computer. Without directlyreflecting the detected emotionally charged behavior to the user(because generally no one wants to be directly accused of or confrontedwith having become inflamed), the match-making service begins toresponsively provide invitations directed to diagnosing the source offrustration (and/or other emotionally charged reaction), calming theuser and alleviating the underlying source of his or her emotionallycharged reaction. For example, one of the chat room invitations flashedto the user after a short cooling off period might be entitled, “Maybeit's only me, but I hate it when my search engine doesn't understandme.” Upon seeing this, the local user may think, ‘Yes, I do too; let mecommiserate with this other chat room member who appears situatedsimilar to me’. In one embodiment, the other chat room member isactually an automated psychology module that tries to coax the inviteduser into venting his or her frustrations and explaining in more detailwhat those frustrations are directed at. This may be done through aseries of pre-scripted question and answer dialogs that are routinelyvaried so users will not readily catch on to the automated nature of thequestioning. The answers that the user provides to the automatedfrustrations vent absorbing module are converted by that module intoCFi's on behalf of the user and sent to the match-making service formatching with other users who have had similar frustrations (and/orsimilar other emotionally charged reactions) and maybe have begun toarrive at solutions. For example, the user may relate to the automatedfrustrations absorbing module, “I am trying to find a research paper onthe theory of taste for my science project and the (expletive deleted)search engine is not getting me to the right resources.” In response,the automated frustrations absorbing module automatically creates CFi's(as if they had instead been created by the user's local machine) thatinclude key terms such as, “frustrated with search engine X resultsabout theory of taste”. In other words, the automated frustrations ventabsorbing module has inserted the emotion-defining keywords that theuser him or herself would not be willing to openly admit to. Inresponse, the match-making service finds chat rooms filled with otherusers facing the same or similar frustrations and/or similar otheremotionally charged reactions and perhaps some that can offer solutions.A second user on one chat room may instantly reply, “Yes, I had sameproblems with search engine X but got much better results with searchengine Y and these alternate search terms”. Other examples of keywordsthat the automated emotions detecting/absorbing module might insert onbehalf of the emotionally charged first user when auto-creating hisCFi's might be: “mad about . . . ”, “sad about . . . ”, “angry with . .. ”, “disappointed with . . . ”, “hurt by . . . ” and so on. These autoinserted, emotion expressing keywords can work to better connect theemotionally charged first user to other users who have or are feelingthe same thing about the associated topic. A machine-implementedautomated method in accordance with the above may comprise the steps of:(a) detecting biometrically or otherwise, emotionally charged activitiesby a user that exceed the user's normal level of emotional engagementwith his or her local client machine and thus indicate exceptionalfrustration or other exceptional reaction to machine provided content;(b) in response to the detection of the exceptional emotionally chargedactivities, inviting the user to a moderated online exchange servicethat is configured to empathize with the user's exceptional reaction anddraw out from the user details about the source of the user'sexceptional emotionally charged activities, (c) using the details drawnout from the user by the moderated online exchange service (e.g., thefrustrations vent absorbing module) automatically generating contentfocus identifying records (CFi's) that identify the drawn out detailseven though the same do not appear as out-ofn-chat content on the user'smachine; and (d) in response to the generated content focus identifyingrecords (CFi's) inviting the user to chat rooms or other onlineexchanges involving other users who are or were similarly exceptionallyemotionally charged about a same or similar topic.

Aside from the system relying on collected biometric data to infer theuser's routine and/or exceptional emotional states or other aspects ofthe user's state of mind, in one embodiment the system allows the userto explicitly indicate his positive or negative interest in, ordisposition about a specific item (e.g., out-ofn-chat room content beingfocused on or inn-chat room content that is being voted upon). In oneembodiment, the user invokes a voting menu (e.g., 336) by right clickingwhile his mouse cursor 335 while it hovers over a specific piece ofcontent, for example one of the search result items in area 330 c. Thelocal machine then responsively unfurls a menu such as 336 whichindicates some of the possibilities for explicitly indicating interestor voting upon pointed to content or otherwise venting frustrations. Thedisplayed options in exemplary pop out menu 336 allow the user toexplicitly vote positively (+Vote) or negatively (−Vote) relating to thepointed to content. The displayed options in exemplary pop out menu 336allow the user to explicitly indicate positive (+Interest) or negativeinterest (−Interest) in corresponding content. In one embodiment, thevoting options (±Vote) are grayed out if the cursor is not inside a chatroom window. Additionally, the displayed options in exemplary pop outmenu 336 allow the user to toggle the interest monitoring alert flag 312on or off for a desired length of time. Although not shown, in oneembodiment the right click options menu (e.g., 336) allows the user toexplicitly indicate a mood shift with regard to what is being displayed.While the illustrated pop out menu 336 provides some examples, in otherembodiments the user may be provided with yet a longer or differentrange of options of things that may be explicitly communicated to theremote on-line matching service, including pop out submenus forexplicitly indicating change of interest, change of vote, change ofmood, intensity of interest or of vote, a desire to browse the hierarchytree (e.g., FIG. 4B) and perhaps thereafter change the topic of interestcurrently assigned to the user, etc.

Referring to FIG. 3B, shown is a second exemplary user screen or userwindow 300′ that can be provided in accordance with the disclosure.Where convenient, apostrophied reference numerals (e.g., 311′, 315′) areused to identify substantially similar on screen elements correspondingto those of FIG. 3A and thus most of these will not be discussed withextensive detail. What is different in FIG. 3B is the presence ofresearch recommendation bars such as a first one, 351 shown under theChat Opportunity A2′ bubble 315 d′.

A second research recommendation bar 352 is shown under the plural chatopportunities bubble 315 c′ where here, the user has mouse clicked on orotherwise activated that second research recommendation bar 352 and thelocal machine has responsively popped open a corresponding matrix menu355. The opened matrix menu 355 of this embodiment provides furtherresearch recommendations in the form of direct or indirect hyperlinksdenoted as Link_(—)11 through Link(s)_(—)43 where these researchrecommendations are for the topic covered by the chat opportunities ofinvitation bubble 315 c′. In this particular embodiment, three chatopportunities or separate invitations are provided in bubble 315 c′,namely, a first invitation C3a deemed appropriate for a user having“Beginner” status or level of sophistication in the relevant topic C; asecond invitation C3b deemed appropriate for a user having “Novice”status (more sophisticated than a mere beginner); and a third invitationC3c deemed appropriate for a user having “Advanced” status (moresophisticated than a novice). The denominations as “beginner”, “novice”and “advanced” are merely illustrative. A variety of differentdenominations and different numbers of them could have been used insteadbased on the topic being covered. For example, if the topic had been apolitical one, the listed denominations might have said:“for-the-proposition”, “against-the-proposition”, and “undecided”, whereagain these are merely examples.

The popped opened matrix menu 355 of this embodiment similarly providesrows with different levels such as the “beginner”, “novice” and“advanced” levels shown in column 355 c. A user may click on the up/downarrowheads of column 355 c to thereby respectively scroll the displayedmatrix section up or down and see more options if available. Heading row355 a segregates the displayed research recommendations into types ofresources, for example where the first offered column links to “blogs”on the topic C covered by bubble 315 c′, where the second offered columnlinks to “news” websites that report on the topic C, where the thirdoffered column links to “white papers” written about the topic C, andwhere the fourth offered column may provide further links to same ordifferent other categories of content sources whose content is directedto the topic C covered by bubble 315 c′. In one embodiment, eachinterior box of the matrix (e.g., that containing Link_(—)11) provides asingle hypertext link directly to the on-topic material. In anotherembodiment, each interior box of the matrix provides a single hypertextlink to a web page that has further links corresponding to the row 355 cand column 355 a descriptors of the matrix 355. In the same or yetanother embodiment, each interior box (e.g., box 355 b that containingLink(s)₁₃ 43) of the matrix may provides plural hypertext links of thedirect or indirect kind. A user may click on the left/right arrowheadsof header row 355 a to thereby respectively scroll the displayed matrixsection left or right and see more columns as options if available.

In the illustrated embodiment, the user has clicked on Link_(—)33 and asa consequence, a new web page frame or window 357 automatically poppedopen in her screen area 300′. Before clicking bar 352 and then utilizingthe offered further research recommendation of Link_(—)33 (a link tocorresponding URL33), the user had only a first web article 317′concerning associated topic C′ (which topic for example might relate tosome thesis the user is developing about say, the historical implicationof the French Revolution—as seen in the user's opened file window 320′).The first web article 317′ provided a first keyword (keywd1) that washelpful for researching the topic and developing the thesis. However,after activating Link_(—)33, the user is automatically introduced to abetter web article 357 on the topic located at URL33 where theintroduced web article 357 is better for any of a number of reasons,including for example that it provides additional useful keywords,keywd2 and keywd3 which the user had not run across before or the newarticle is more in line with the user's thesis 320 b′, the new articlehas a better, more on-topic graphic D embedded in it, etc. The user maynow use the additional keywords, keywd2 and keywd3 to conduct yetfurther searches in line with his thesis 320 b′. Without the help of theautomatically suggested further research recommendations 355, the usermay have been stuck and not making rapid progress developing his thesis320 b′. By accepting the automatically generated offer for thesuggestions (by clicking bar 352) and by selecting a suggestion in-linewith her needs (e.g., advance white paper) the user has now moved to anew level of collected knowledge for his chosen thesis.

It is to be noted in the hypothetical example of FIG. 3B that the userwas not explicitly asking for further research recommendations (e.g.,355). Instead, she may have been actively typing away in current editingregion 320 d′ of word processing document 320′. The benign spywareexecuting in the background on her client machine detected that the userwas intensely focused upon the content of current editing region 320 d′.The benign spyware had also earlier detected and reported to thematch-making system (the MM-IGS) that the user's topic of interest wasrelated to the thesis listed in region 320 b′. The match-making systemtransparently determined that one or both of chat invitations 315 c′ andfurther research recommendations 355 should be automatically offered tothe user at this time. The invitations and recommendations (bar 352)drifted into the central radar scope area of the user's scrollinginvitations banner. The user noticed it (perhaps because an audibleurgency tone was sounded) and accepted the offer of recommendations (byclicking on bar 352 and then clicking Link_(—)33). Magically, the userdiscovers that the linked-to new web page 357 is different from what theuser has found thus far, and more on-topic and/or in-line with histhesis 320 b′.

Of course it is not by magic but rather by deliberate execution ofbackground machine-implemented automated processes that all thisoccurred. Referring to FIG. 3C, assume that the user of FIG. 3B is Sally121″ (shown in upper left of drawing). Because the benign spyware wasturned (Interest Monitor=ON) in Sally's local machine, it was providinga CFi upload stream 361 to an assigned domain and topic lookup service(DLUX) 362 executing in the cloud. Sally's uploaded CFi data stream 361included the URL of first web article 317′ of FIG. 3B and the dominantwords 320 c′ of document 320′. From this, and optionally in combinationwith Sally's domain specific profile 506 a″ and/or Sally's personhoodprofile 505 a″, the in-cloud DLUX 362 automatically determined thatSally's current topic of interest is most probably a topic C which iscovered by a system topic node identified as 450′ and represented by atopic node data object stored in system storage (to be described shortlybelow). The DLUX 362 points to this node 450′ by way of pointer 363. Thepointer 363 might reference the node's globally unique, node ID tag 450a′ and/or the node's current position (e.g., polar coordinates) 450 pcin a predefined topic space. A more detailed description of domain andtopic nodes (see FIG. 4B) and DLUX services (see FIG. 4A) will followshortly.

For now it is sufficient to understand that, just as Sally's on-screenactivities caused a first DLUX 362 associated with Sally 121″ to point363 to topic node 450′; there are other users of the system (bottom leftcorner of FIG. 3C) whose respective CFi data uploads 371 cause theirassigned DLUX services 372 to also point 373 to the same topic node450′. The CFi data uploads, 361 and 371, of all the users linked to thatnode 450′ are collected and ranked. Some URL's or other CFi data may bescored as much better than Sally's current CFi data 361. Those higherscored URL's or other CFi-supplied resource identifiers may then beautomatically fed back to Sally 121″ (e.g., from unit 369 of FIG. 3C) asrecommendations 355 of FIG. 3B. Additional details will be providedafter FIGS. 4A and 4B are described. It is to be understood,incidentally, that chat invitations (e.g., 315 c′ of FIG. 3B) andrecommendations (e.g., 352/355 of FIG. 3B) for on-topic contentresources are not interdependent on each other. Sally's client machine(e.g., whose screen area 300′ is shown in FIG. 3B) could have displayeda radarscope like flow of recommendation bars, 351, 352, 353, etc. (withthe middle one enlarged) and no chat invitation bubbles like 315 c′ and315 d′ or vise versa. If both are displayed, Sally can elect to accept achat invitation (e.g., C3b) without accepting a resource recommendation(e.g., Link_(—)33) or vise versa. Or she can elect to accept both.

Referring back to FIG. 3B, so far it has been implied thatcontent-describing CFi upload data is generated in response to what theuser is currently looking at (and/or otherwise actually perceiving).However, it is within the contemplation of the disclosure toautomatically generate CFi upload data based on certain types of contentthat the user is currently NOT looking at (and/or otherwise perceiving)where that content is of such a nature that it may be taken as beingimpliedly currently displayed on the user's screen (even though it,e.g., roller 358 and frame 359, is/are not being displayed) and as beingimpliedly currently focused upon by the user (even though it, e.g.,roller 358, frame 359, is not being currently focused upon). Morespecifically, the user may have one or more pressing, to-do files suchas a planning calendar file (example shown at 359) or amust-meet-and-confer list (example shown at 359) or similar other suchdata stored in his client machine (e.g., in his portable PDA) and/or inanother means accessible to the match-making and invitations-generatingsystem (MM-IGS). These pressing, to-do files may set forth places andtimes of already scheduled meetings, events, conferences and the likewhich the user is committed to attending or has a possibility ofattending and/or to-be-scheduled meetings which the user has a pressingneed to schedule and make. More specifically, the optional or pressingto-do planning data may indicate the times and/or places of variousevents and/or identifications of persons that need to be met with, aswell as some information that hints at or explicitly defines one or moretopics to be dominant at the meeting, conference or other event. Forexample, item 359 of FIG. 3B represents a not-being-displayed personalcalendar of the owner of client machine (having display 300′) where thepersonal calendar 359 is stored in the client machine (300′) and/orelsewhere (e.g., in a secured in-cloud account settings file of theuser) and is accessible to CFi data producing software (e.g., 205 a ofFIG. 2A) for the purpose of producing corresponding CFi data at, orbefore, the planned time of the event for uploading to the MM-IGS in amanner mimicking a hypothetical situation of the user being then focusedupon the calendared or other pressing information that relates to anoccurring or possibly soon to occur event. In one embodiment, the useris provided with line item veto capability whereby the user can hidefrom the CFi data producing software any desired one or more of theplanned events or other pressing matters and thereby block the softwarefrom producing CFi data for that event or other pressing matter. Inother words, the non-displayed calendar data of “this week” item 359 isuploaded only with approval from the user. In one embodiment, prior toCFi upload, the user's client machine flashes a warning that thecalendared or other pressing matter information is about to be uploadedand gives the user an opportunity to block the upload.

In terms of a more specific example, let it be assumed that the user'snot-currently-displayed calendar 359 shows that on Monday of this week,the user plans to be at (or has a good probability of being at) theMoscone Convention Center in San Francisco for a 9:00 AM eventconcerning topic A. When the time period for the event approaches (sayat around 8:00 AM on that Monday), his client machine begins toautomatically generate CFi upload data indicating increasing focus bythe user upon topic A and the event at Moscone Center, and perhaps alsowith the CFi uploaded data providing some keywords or other subtopichints extracted form a “Details” section of the calendared event record(e.g., a database record). Other CFi data generated by the user'smachine, such a GPS current location, may verify that the user is indeednear the location of the Moscone Convention Center as the time for theevent (e.g., 9:00 AM) approaches. Similar CFi data will be automaticallygenerated from, or on behalf of the client machines of other systemusers who are also planning to be at the same event and/or at the samevenue. As a result, chat room invitations may be automatically sent outto those of the event attendees who have sameness or substantialsimilarity of implied topic(s) of focus and/or chat co-compatibility. Inone variation, the uploaded CFi data of the user of the illustratedmachine (300′ of FIG. 3B) indicates that this first user is concurrentlyfocused upon topic C (of displayed window 357). In that case, the morestrongly suggested chat invitations may be to rooms where the otherinvited users are also currently focused upon topics A and C and theMoscone event venue (and optionally where they have personalityco-compatibility for chatting online or in person).

The portable client machine (e.g., 3G-cellphone, PDA, etc.) of many auser will include a GPS (Global Positioning Satellite) or otherautomated self-locating subsystem. And as mentioned elsewhere herein,detailed location information about the client machine's currentlocation can be at least periodically uploaded to the match-making andinvitations-generating system (MM-IGS) alone or in combination withother CFi data. Thus the MM-IGS can (if given permission by the user todo so) keep track of the current locations of all online system userswho have their BlackBerry™ or other PDA turned on with the GPS or otherautomated self-locating subsystem active. Additionally, in the pressingmatters files of many a system user there can be a contacts set ofdatabase records that identify one or more persons whom the user wantsto personally meet with regarding a pressing matter, for example oneinvolving topic A. The not-currently-displayed contacts roller 358 shownin phantom in FIG. 3B has a contact named “Sam” identified as someonethe machine's user wishes to soon meet with personally to discuss topicA, and perhaps more so, to personally discuss certain details of topic Awhich are identified or hinted at in a “Details re Sam & topic A”section of the record shown as part of roller file 358 and shown ascurrently most pressing up against (but often not being displayed) ondisplay 300′.

In one example, it just so happens that Sam is at the Moscone ConventionCenter at the same time that machine user Sally (121″) is at that venueand opportunistically they both have a same open time slot to meet inperson and discuss topic A. However, the Convention Center is so big andso crowded that neither spots the other. The MM-IGS service though, alsoknows they are both there at the same time from the GPS or otherself-locating information provided in their uploaded CFi data and italso knows that the in-person meeting re topic A is a pressing currentfocus matter on both their minds because each has allowed theirautomatically generated CFi upload data to include high prioritypressing contact items (e.g., that of roller 358) even though the useris currently not looking at that content. In response to its automateddetection that Sam and Sally are in short-travel time proximity of eachother and at least one, if not both users, urgently want to set up thein-person meeting regarding topic A, the MM-IGS automatically generatesa meeting proposal (similarly to the way that chat room invitations aregenerated) and sends the meeting proposal to both with an invitation toa private chat room where they can iron out details of the meeting(e.g., exactly where and when). Thus it is seen that automaticallyuploaded CFi data can be useful for producing not only online meetingsin chat rooms and the like (by way of invitations), but also forproducing in-person meetings even if the system users do not at themoment have it in their mind that they can meet at the time. Of course,in one embodiment, current user mood is factored into such automatedproposal of opportunistic meetings. One of the users may have indicateddirectly or inferentially that they are currently not in a good mood,and if so, the system may include knowledge-base rules that define whenthe opportunistic meetings should not be proposed due to a bad mood byat least one user and/or when the opportunistic meeting should beproposed (due to extreme urgency) despite the bad mood of one of theusers. Also, although not shown in item 358 of FIG. 3B, it is within thecontemplation of the disclosure to include priority indicators in thepressing contact records of files like hidden 358 and to have the systemautomated arbitrate among competing items based on priority. (Forexample, Sally's pressing contacts roller stores another desiredin-person meeting with Sharon and Sharon is also at the conventioncenter, but Sam's priority is higher. So the system first automaticallyproposes the higher priority meeting, and if that doesn't come tofruition, the system may then automatically propose the next highestpriority meeting if it is opportunistically possible given the currentlocations and/or moods of the various parties.)

Sometimes users who are at a meeting, show, etc., will turn off or putaway their cellphone, PDA or other CFi uploading device and forget toturn it on or pull it out, perhaps for a number of hours. That meansthat their last uploaded CFi data will become relatively old and theMM-IGS system may wrongly interpret the event (cessation of CFi uploads)as indicating that they have lost interest in certain topics (due todecay of exhibited interest) when this is not at all the case.Accordingly, in at least one embodiment, one of each user's profiles(typically the CpCCp) includes a last known state and interests record(not shown) that records the last set of content items and intensity offocus on them that were detected for the given user when the device wasturned off (or apparently put away in a purse, jacket pocket, or otherdarkened enclosure). When the user turns his or her device back on (orpulls it back out into the light as detected by an integrated backgroundlight detector), the data in the last known state and interests recordis treated as if it had just been uploaded into the cloud. In otherwords, upon boot up of a user's primary client machine (or pull out backinto the light), the system assumes that the user is in the same stateas they last were even if the user does not immediately begin looking atcontent that is on a same or similar topic as that which was last lookedat. For example, the user may first look at the most recent news storieseven though the user has not lost interest in the on-mind topic that waslast on his or her mind when they shut off the machine or put it away.

Referring now to FIG. 4A, shown here is a networked system 400 inaccordance with the disclosure wherein a plurality of distributed datacenters, 410, 420, etc. are coupled via a network 430 (e.g., theinternet) to plural client machines 440. One or more services may beprovided within each of the data centers, 410, 420, etc. Work load forservicing clients may be adaptively redistributed among the data centersdepending on user activity among the numerous client machines 440 thatcouple via the network 430 and depending on availability of servicesresources within the various data centers at different times of the dayor night at different geographic locations.

Services provided within the data centers may include the following: anAccess (client access) and Accessible-Resources Monitoring Service(AARMS) 411, a User Accounts-management Service (UAS) 412, aDomains/Topics Lookup Service (DLUX) 415, a plurality of Domain-specificMatching-making Services (DsMS) 416, and a Chat Rooms management Service(CRS) 418. The servers (virtual or actual) which provide these servicesand the corresponding software modules that provide these services maybe coupled via a secured data center internal backbone 417 to a varietyof center-accessible data stores, including a Global Services DirectoryStore 431, a User Accounts Data Store 432, a Domain/Topics hierarchyconfiguration store 435 and a historical Trending data store 437. Theservices providing modules 411-418 and data stores 431-437 (e.g., harddisk storage banks) couple to an unsecured network (e.g., internet) 430via a protective firewall 419 a and through one or more data routers 419b (collectively shown as 419). A trusted (non-open) high speed dedicatednetwork or virtual private network (VPN) 439 interconnects the backbone417 of a first of the data centers 410 to that 417′ of a next datacenter 420 and so on so that resources can be shared and reallocatedamong data centers depending on resource availability and user demands.

Referring first to the Domains/Topics Lookup Service (DLUX) 415, it isto be understood that a large number of topic domains and topics andsubtopics may be defined either by system operators or by the servicesusing public (clients 440). The topic domains, topics, subtopics and soforth are represented by topic-representing data objects or node objectsstored in system memory (e.g., 435). Chat rooms may be pre-assigned ordynamically re-assigned (migrated) to specific domains and/or topics,subtopics, etc. or newly created to serve such topic areas depending onuser population interest in the respective topics. A same chat room maybe pointed to by different topic nodes if the chat room is currentlyproviding transactions related to the topics of the plural topic nodes.See briefly the pointers 469 to corresponding chat rooms (CR's) 469a-469N in hierarchy tree 401 of FIG. 4B, where room 469 a is pointed toby another topic node in addition to being pointed to by topic node 460.The system operators may establish an initial or seed set of Domains andtopics on a hierarchical basis and position them as desired in aninitial or seed topic space (see briefly FIG. 6). Examples of seedDomains may include: News, Health, Jobs, Entertainment, Finance, Mapsand Travel, Personals, and so forth. An example of aDomain/Topic/Subtopic hierarchy might be: Sports/Football/Quarterbacks,Another example might be: Entertainment/Movies/Stars/Male. Hierarchicaldefinitions of topic, subtopic, subsubtopic, etc. as nested logic treesmay extend to whatever length deemed appropriate by system users and/orsystem administrators. System users with voting rights may vote and cometo collective agreements on what unique primary names (e.g., 451 of FIG.4B) and/or alias names (e.g., 452 of FIG. 4B) are to be given to eachnumerically identified domain (e.g., see 450 a of FIG. 4B) and/or itsnumerically identified subtopics. System users with voting rights mayalso vote on where in a prespecified topic space the node should bedeemed to be located (e.g., see briefly, polar coordinates storing area450 pc of FIG. 3C). Amount of nonvolatile machine storage dedicated toeach node, be it a domain, topic, etc. may be determined though use andon the basis of which domains require the most bandwidth for servicesupport and which can provide satisfactory service to users whilerequiring less bandwidth. The user population may cause new Domains tobe dynamically added to the root (402 of FIG. 4B) of a given data center(or globally) and others to be dropped from that data center (where suchdropping is not allowed in some embodiments) depending on the whims ofthe user base assigned to or using that data center (e.g., 410, 420) orthe system in whole. The root at each data center will include acatch-all domain (see D0 of FIG. 6) and each domain subtree will includea catch-all child for absorbing miscellaneous chats if none of thespecific domain or topic nodes yet apply. The root catch-all domains maybe identified chronologically and geographically, for example as,DataCenter456/root/General_Domain/catch-all_activities_of/today's date.

In one embodiment, each of the distributed data centers 410, 420, etc.in system 400 of FIG. 4A has a limited initial Domain hierarchy definedin its respective Domain configuration store 435, 435′, etc. bycorrespondingly stored digital data objects that represent nodes of thehierarchy and provide an indication of how they are logicallyinterconnected one to the next. Each domain specified in this initialhierarchy may have a pre-assigned, whole number navigation meta-tagidentifier (e.g., 405, 407 in FIG. 4B) which might correspond tohierarchy navigation meta-tag codes 216 f of the CFi data structure ofFIG. 2A. Topics and subtopics under each main domain name may bedesignated by decimation (thus separating domain.topic.subtopic withdecimal points) and/or use of slash separators (e.g.,domain/topic/subtopic/etc.). In this way, the topic hints provided inpulled current focus indicators (CFi's) may be quickly matchednumerically to nodes defined in the Domains configuration stores 435,435′ of the various data centers. Not all data centers need to haveidentical domains and/or topics defined in their respective Domainsconfiguration stores 435, 435′. (However, in at least one embodimentexact mirroring of domain and topic definitions from one data center tothe next is required and is provided for by a crawling backgroundservice that synchronizes all data centers. In an alternate embodiment,only a predefined subset of the domains and topics hierarchy tree—forexample, a predefined angle sweep in FIG. 6—needs to be replicatedacross all data centers. Redundancy allows for reconstruction of data ina failed storage device of a given data center if such should happen.)As an example of a case where full replication is not provided, considera relatively esoteric topic may be serviced at only two data centersbecause there are only a handful of users throughout the world who arecurrently discussing it. These people already know the two places (datacenters) where the esoteric one node is redundantly located and know howto navigate to each of them. Essentially no one else needs to know. Onthe other hand, domains and/or topics that are very popular with thegeneral public (e.g., world cup soccer) may be replicated at every datacenter around the world or at least throughout specific countries. Eachpre-designated domain identification number and optional topic numbermay also have a preconfigured collection of reusable chat rooms (459,479) reserved for it and always available for absorbing incoming userswho accept invitations for that domain and topic. Depending on whether apremium service has been subscribed to or a general free-for-allservice, respective client computers (e.g., 440A, 440B, 440C, etc.) canaccess all or a non-premium portion of the Domains configuration store435 to look up what domains and topics are currently available at anearby or remote data center and they can even browse through publicones of the chat rooms covered by accessed hierarchy nodes (e.g., 450,460 of FIG. 4B). These looked up domain and topic hierarchy structuresmay be displayed to local users by their respective client machines(e.g., 440A, 440B, etc.) for use in creating the user's DsCCp profiles(see column 183 of FIG. 1C). In one embodiment, all users or subsetsthereof (e.g., premium subscription users) are enabled to also see ontheir displays the hierarchy tree (or authorized parts of it) projectedonto a polar topic space such as that of FIG. 6. In one embodiment,beyond each topic node pointing to, or being otherwise logically linkedto on-topic online chat rooms (e.g., via linking structures 459, 469,479, 489, etc.), one or more of the topic nodes each point to (e.g., viapointer structure 459X), or otherwise logically link to on-topic otherresources such as on-topic online videos, on-topic nonchat web sites(e.g., on-topic blogs or blog comments), on-topic reading lists and toother on-topic content providing mechanisms (e.g., TV shows, books,movies, etc.). The nonchat other resources that are pointed to (e.g., bypointer structure 459X) may include proposals for online or in personmeetings by two or more of system users where the proposed meeting isdefined as covering at least the current topic of the given topic node.In one embodiment, participants inside chat rooms pointed to by thegiven topic node (e.g., node 460) can vote on what nonn-chatroom contentthe given node will point to (e.g., which online video streams, whichnews or editorial items, etc.). In order to avoid illustrative clutterin FIG. 4B, these links from the node to the nonn-chatroom on-topiccontent are not shown elsewhere except for 459X of node 450. However,they are understood to be similar to 459, 469, 479, 489 etc., exceptthat they point to nonn-chatroom on-topic content.

In one embodiment, system servers scan the catch-all Domain andcatch-all topic bins (not specifically shown) in the data centers (410,420, etc.) and when the servers detect that there is sufficient chatactivity related to a set of CFi identifiers (sufficient topicclustering) where the set of CFi identifiers are not already assignedtheir own Domain and/or Topic identification numbers, the system serversautomatically create such new specific domains, topics, etc. and assignunused navigation meta-tag numbers and/or topic space coordinates tothem and publish the results to the relevant users via the domainsconfiguration stores 435 in the respective data centers and/or via emailadvisement messages. The user community will be allowed tocollaboratively name Domains and/or topics and assign them to branch andsub-branch (child node) locations in the tree-like Domain hierarchy. Inone embodiment, only users subscribed a sufficiently high premium levelof service will be allowed to participate in domain/topic naming andnode placement within the hierarchy. In an alternate embodiment,participation in domain naming and placement activities will beelectable by the user. Some users won't want to be bothered. Others maytake pride in being involved in process. Any set of CFi hint values seenoften enough to warrant automatic creation of their own Domains willprobably be popular enough to have some percentage of the user communityinterested in the naming and categorization process.

Aside from optional user participation in domain/topic node naming andcategorizing (node placement in the hierarchy tree and/or nodepositioning in topic space), system administrators may: review andrevise Domain names and/or their categorizations; and specify that adynamically created Domain should be included in the nonpremium list ofpublished Domain names which every user can explicitly specify in his orher DsCCp profiles. As catch-all chat rooms are created and users inthem gravitate or cluster their interchanges toward specific topics, thechat rooms may be automatically re-associated with a specific Domain IDand/or topic ID based on matching CFi values of new users who areinvited into and join those catch-all rooms.

Aside from traditional domain names such as News, Sports, Weather,Traffic, etc., it is within the contemplation of the disclosure to havespecial activity domain names. A first example is a domain node named:“What is recommended as an activity IF My Current Location is:”. Underthis there will be topic nodes including those bearing the names ofmajor geographical areas or population centers such as, for example,“New York City”, “London”, “Paris”, “California”, etc. Under each ofthese (or over each of these) there will be sub-topic (or super-topicnodes) including those bearing the identities of different time ranges,such as for example: “And IF My Current Time is Weekday Morning”, “AndIF My Current Time is Weekend Lunch”, And IF My Current Time is NationalHoliday”, etc. Under each of these (or over each of these) there will besub-topic (or super-topic nodes) including those bearing the identitiesof different situational conditions such as for example: “And IF MySurrounding Weather Condition is Very Hot”, “And IF My SurroundingWeather Condition is Raining”, etc. Under each of these will besubsidiary activity nodes bearing the identities of different activitiessuch as for example: “Restaurants to Eat at”, “Shows to see”, “Movies tosee”, “Museums to visit”, “Sight Seeing Tours to take”, “Nature Hikes totake”, etc. Since in one embodiment, each users portable client machine(e.g., cell phone) is periodically uploading the user's GPS location tothe match-making system and the time of day, the system canautomatically make activity recommendations given that the system alsohas a copy of the user's current personhood profile (CpCCp) and thelatter provides demographic information about the user as well asvarious likes and dislikes (e.g., favorites insert 154-7 a of FIG. 1B).The match-making system can then automatically generate invitations tochat room discussions among demographic peers as to the recommendedactivities at that locale given the time of day, week, month, year andcurrent situational conditions. Additionally, as nonchatrecommendations, the system can automatically generate pointers torecommended restaurants to eat at, nature hikes to take, etc., all basedon information uploaded form the user as part of his routine CFiuploads. As a consequence, the system appears to function as anautomatically invoked, automated tour guide.

As yet another example special activity domain names, it is within thecontemplation of the disclosure to have a domain node named: “What isrecommended as an inter-organization activity IF an Organization ICurrently Belong to is:”. Under this there will be topic nodes includingthose bearing the names of major corporations, college fraternities,honor societies, political parties, etc. Under each of these (or overeach of these) there will be sub-topic (or super-topic nodes) includingthose bearing the identities of different time ranges, such as forexample: “And IF My Current Time is Weekday Morning”, “And IF My CurrentTime is Weekend Lunch”, And IF My Current Time is National Holiday”,etc. Under each of these (or over each of these) there will be sub-topic(or super-topic nodes) including those bearing the identities ofdifferent situational conditions such as for example: “And IF MySurrounding Weather Condition is Very Hot”, “And IF My SurroundingWeather Condition is Raining”, etc. Under each of these will besubsidiary activity nodes bearing the identities of differentinter-organization activities such as for example: “Meetings to Attend”,“Open Collaboration Projects to Join” and so forth. Since in oneembodiment, each user's CpCCp includes a listing of organizations he orshe currently belongs to and since the user's portable client machine(e.g., cell phone) is periodically uploading the user's GPS location tothe match-making system and the time of day, the system canautomatically make activity recommendations given that the system alsohas a copy of the user's current personhood profile (CpCCp) and thelatter provides demographic information about the user as well asvarious likes and dislikes (e.g., favorites insert 154-7 a of FIG. 1B).The match-making system can then automatically generate invitations tochat room discussions among demographic peers as to the recommendedorganization-sponsored activities at that locale given the time of day,week, month, year and current situational conditions. Additionally, asnonchat recommendations, the system can automatically generate pointersto recommended restaurants to eat at where fellow organization membersare likely to be, golf course to golf at where fellow organizationmembers are likely to be, etc., all based on information uploaded fromthe user as part of his routine CFi uploads. As a consequence, thesystem appears to function as an automatically invoked, automatedorganizational activity coordinator who shepherds the user toappropriate organization sponsored activities as a function of theuser's current situation. These are just examples and yet furtherspecial activity domain nodes may be provided as functions for exampleof how the user is currently feeling (ready for exercise with peermates, ready to go dancing, hiking, etc.). In other words, online realtime chat room meetings are just some of many possible activities thatusers of the system may automatically receive invitations to and/orrecommendations for and/or proposals for based on the CFi data uploadsthat the user's current client machine(s) are automatically uploading tothe match-making system even when the user is not conscious of suchuploads taking place (although of course, the user's permission for thebenign spyware to be active is obtained and/or repeatedly reaffirmed insome way or another so as to respect the user's privacy rights).

As yet another example special activity domain names, it is within thecontemplation of the disclosure to have a hybrid domain node named forexample: “What is recommended as an inter-organization activity AND formy current location where the organization/-location pair is as follows:(e.g., Society of Internal Medicine Physicians and Nebraska)”. One ofthe activities might be to discuss a current observation of new symptomsamong patients (e.g., salmonella poisoning) in a given geographicregion. It is within the contemplation of the disclosure to limitinvitation into certain chat rooms only to individuals who are licensedin a particular art (e.g., medicine, law) and/or are credentialed in aspecified specialty (e.g., infectious diseases) and/or are practicing ina specified geographic region (e.g., Nebraska). This type of nodalcategorization allows specialist to spot unusual developments germane totheir location and their specialty. In one embodiment, the users mayexplicitly specify that they want invitations limited to this type ofnodal categorization or their CpCCp and/or DsCCp may specify apreference for this type of nodal categorization.

In one embodiment, certain domain nodes are expected to be morepermanent fixtures of the hierarchy tree than others, and as such, thesemore persistent domain nodes are assigned smaller coordinate angles inpolar topic space than domain nodes that are expected to be lesspersistent and more volatile in nature (e.g., fad domains that come andgo). Among the certain domain nodes are expected to be more permanentfixtures are: (1) Those dealing with personal health issues, includingthose having chat rooms dedicated to specific health maintenance topicsand/or disease treatment and/or management issues. Topics under theHealth domain node may include those where each chat room is alwaysstaffed by or periodically visited by a credentialed health careprovider (e.g., a licensed doctor or nurse). Further among the certaindomain nodes that are expected to be more permanent fixtures are: (2)Those dealing with children, including those having chat rooms dedicatedto specific educational needs of children and/or specific behavioralcontrol issues associated with caring for and raising children. Topicsunder the Children domain node may include those where each chat room isalways or staffed by or periodically visited by a credentialed educatoror child psychology expert. Further among the certain domain nodes thatare expected to be more permanent fixtures are: (3) Those dealing withjobs and career choices. Topics under the Jobs/Career domain node mayinclude those where each chat room is always or staffed by orperiodically visited by a credentialed career advisor. Further among thecertain domain nodes that are expected to be more permanent fixturesare: (4) Those dealing with domestic pets (e.g., care and training ofdogs, cats, etc.) wherein topics under the Pets domain node may includethose where each chat room is always or staffed by or periodicallyvisited by a credentialed animal care expert; (5) Those dealing withvacationing and traveling wherein topics under the Travel domain nodemay include those where each chat room is always or staffed by orperiodically visited by a credentialed travel and vacationingconsultant; (6) Those dealing with business issues (e.g., investmentrecommendations, company management etc.) wherein topics under theBusiness domain node may include those where each chat room is always orstaffed by or periodically visited by a credentialed businessconsultant; (7) Those dealing with information research issues (e.g.,best search strategies) wherein topics under the Research domain nodemay include those where each chat room is always or staffed by orperiodically visited by a credentialed research consultant; and (8)Those dealing with current events in general and having current eventdiscussion rooms dedicated to specific newspaper publications. Furtheramong the certain domain nodes that are expected to be more permanentfixtures are: (9) Those dealing with product and shopping advice (e.g.,what is/are best computers, cars, etc. to buy in given price rangeand/or what is/are best stores, vendors, dealerships to use forobtaining desired products and/or services); and (10) Those dealing withsports (e.g., and having topic nodes dedicated to discussing favoriteteams, favorite players, favorite games etc.)

As mentioned above, chat rooms operating under the root catch-all nodeor under the catch-all node of a domain typically have a specific topicassigned to them. However, over time, participants in the catch-all roommay begin to cluster around a specific topic. FIG. 4D flow charts onemachine-implemented process for automatically converting catch-all nodeswithin a hierarchy tree into named and categorized nodes. It is to beunderstood that each domain node (e.g., 450, 470 of FIG. 4B) of oneembodiment can have one or more “catch-all” child nodes with no specifictopic name (e.g., 461) beyond that of its parent node and/or no specifictopic specification (e.g., 463) beyond that of its parent node. A“catch-all” child node will however have a unique node ID tag (e.g., 450a, 460 a, etc.) in one embodiment, where the node ID tag allows it to betraced as it migrates form catch-all status to another status. It is tobe also understood that there will be a “catch-all” domain node (notshown in 4B, see instead D0 of FIG. 6) under the tree's root with nospecific domain name (e.g., 451) and/or no specific domain specification(e.g., 453) other than “catch-all” or “none” or something of thatnature. The “catch-all” domain node will also have a respective uniquenode ID tag. Small groups of chat partners who have no specific node tobe matched to, and yet are co-compatible with one another and/or arefocused upon same or similar content, may be huddled (clustered) intoone of the no-name chat rooms either under a no-name, “catch-all” nodeor even under a named node. (A catch-all node can have a uniqueidentification number even though it has no specific name or expressedmission statement.) As the population of a “catch-all” room evolves, andperhaps grows and acquires unique room characteristics, this growthand/or increased activity by its users may indicate a need for movingthe node or bifurcating it to position the moved/split room under apreexisting node or to even create a new node and position it there soas to thereby produce a corresponding, named and specifically placed noncatch-all room placed under the target node (could be a new domain)within the system hierarchy tree. The method of FIG. 4D seeks out such“catch-all” rooms for the purpose of automatically evolving thestructure of the system hierarchy tree to match evolving needs of theuser population. When step 441 is entered via entry path 441 a, theprocess points to the root's catch-all domain node and sorts the chatrooms (similar to 479) running under that node according to current roompopulation, current room activity level and/or current intensity of userengagement with that room. In one embodiment sorting of chat roomsrunning under a catch-all also scores the amount of topic spaceclustering (both recent clustering and over-time trended clustering)that takes place in that room. The concept of topic space clustering hasalready been described above with reference to FIG. 6. To recap,recently uploaded CFi hints of Sam, Sally and Larry (users 611, 621,651) are processed by a DLUX service and the DLUX outputs are averagedor otherwise combined to provide a mapping of each user's apparentpoints of most likely interests on top of the topic space (600). Thencloseness of mapped topic (e.g., distance 625) is automaticallydetermined as between users. This determination of closeness (625)between users can indicate that some users are more closely clustered toone another and to a specific point in topic space than they are toother users or to the point locations (cross hairs in FIG. 6) of nearbynodes. When a predetermined proportion of users within a given catch-allroom are determined to be closely clustered to one another in topicspace (e.g. 600) for one or both of recent CFi values and long terms CFivalues, the room receives a high clustering score. If users within agiven catch-all room are determined to not be closely clustered to oneanother in topic space (e.g. 600), the room receives a relatively lowerclustering score. The top of the sorted list (whose sort can be based ontopic clustering and/or other sort keys) then identifies a room withgreatest recent or longer term focus on a specific topic, greatestpopulation, significant room activity and/or significant user intensityand thus one that may warrant being migrated sooner rather than later toa more specific node rather than being kept under the auspices of acatch-all node.

An example of how this might come to be, may be helpful. Suppose a newand previously unknown celebrity pops into the public consciousness.Let's call him, Harry the Hairdresser (fictitious name here). He becamefamous overnight because a politician mentioned him and/or because hewon a popular talent show (e.g., American Idol™) or for whatever reason.Suddenly everyone is talking about Harry the Hairdresser, about how wellhe sings or dances, about a new hair style he just introduced, about howhe affects an ongoing political debate, etc. Yesterday, there were nonodes in the system hierarchy tree regarding the topic of Harry theHairdresser. Today, the catch-all domain node is swamped with new chatrooms, all talking about Harry the Hairdresser. It behooves the systemto move at least the more populated and more active ones of these roomswhose topic of discussion clusters around Harry the Hairdresser tospecific domains and/or topic or subtopic nodes or to create new nodes(with node ID tags) for these rooms so as to better serve the growingnumbers of users logging in to talk about Harry the Hairdresser. Whilethe overnight sensationalism of Harry the Hairdresser may be oneexample, there could be other catch-all discussions about esoterictopics where the popularity of the topic slowly grows, first perhaps ata creepingly increasing slow rate but then approaching an exponentialrate. This too should be automatically identified and dealt with beforeit becomes a bigger problem (e.g., in that it swamps the catch-alldomain node and services that focus on serving that node).

Just as Harry the Hairdresser (fictitious name) may explode intonotoriety overnight, he may also disappear into obscurity just a asrapidly or ebb away slowly over time. At some point after his rise andpeak, the system may become filled with unused nodes (no active chatrooms for a long time under those nodes) or redundant lightly populatednodes (some chat rooms, but hardly used and having substantially similarattributes) dedicated to the Harry the Hairdresser topic. In order toavoid waste of system resources (e.g., storage, etc.) on topics that areno longer as popular as they once may have been, the system may includebackground garbage collecting or compressing service modules that crawlthrough the data centers at off hours, locate long unused nodes (orunused chat rooms under those nodes) and delete them and/or locatelightly populated nodes or chat rooms (e.g., those whose usage in termsof number of participants, intensity of participation, etc. are belowsystem defined thresholds) and try to merge the same with othertopic-interrelated nodes and/or rooms that are also lightly populated.In one embodiment, a history is kept of each node at least by its uniquenode ID tag (see 450 a of FIG. 4B) so that it can be determined when orwhere the node was first created, how it grew and migrated about thehierarchy tree and also when and/or where its popularity began todecline, as well as when the node was deleted if such happens. In oneembodiment, advertisers or other such entities may subscribe to a trendreporting service that automatically informs them of when certain topicsreach peaks of popularity and then begin to decline. The information isobtained from the system background garbage collecting or compressingservice modules (not shown) as well as node creating and/or migratingservice modules of the system. This information may allow such entitiesto time their market activities to rises, peaks and declines of varioustopics of interest among system users.

Step 442 looks at the not-yet migrated room (e.g., catch-all room) withthe highest score on the list due to summed and optionally weightedscoring factors such as recent or long term topic clustering within theroom, number of participants in the room, level of user activity in theroom, intensity of user engagement with the room and trending history ofgrowth for these or other factors. Step 443 tests for whether the scoreis above a predetermined threshold such that migration is warranted. Thehigher scoring rooms in the sorted list that was formed by step 441 maywarrant migration ahead of lower scoring rooms. A point of diminishingreturns may be reached where the system determines it is not worthwhileto move the next room on the sorted list to another place on thehierarchy tree (or to another location in the topic space of FIG. 6) dueto the room's lower level of topic clustering, the room's current smallpopulation, low activity rate and/or lack of intense user engagement inthe room's uncategorized topic. If a room's population, activity, etc.,dwindles down towards one or another of predetermined minimums, aseparate automated scavenger process may delete the room from the catchall domain (close it down due to lack of interest) or merge it withanother still-small catch-all room having similar room characteristics(similar long term topic clustering and/or similar room CpCCp or roomDsCCp averages). If the result of test 443 is a No, then control ispassed to step 443N. Here, because all of the sufficiently largecatch-all rooms under the root's catch-all domain (D0 of FIG. 6) havebeen exhausted by steps 442 and 443 (at least for this current goaround), step 443N terminates the “For each” loop of step 442 and itcauses the process to point to the catch-all node of a next one ofpresorted domains (e.g., 450, 470 of FIG. 4B; or D1, D2, etc. of FIG. 6)listed under root. The domains may be presorted according to userpopulations and/or topic clustering with the most populated and/or mosttightly clustered one appearing first. Path 441 b causes the algorithmto be repeated for the catch-all node(s) in the next non-catch-alldomain. When all or the larger of the non-catch-all domains have beenexhausted, the process will revert back to entry path 441 a and beginall over again with the catch-all domain (D0) and the biggest and mosttightly topic clustered catch-all chat rooms currently running underthat root domain.

If the result of test 443 is a Yes, then control is passed to step 443Y.In one embodiment, the room is marked as “warrants migration” and aseparate migration handling thread picks up the task while the “Foreach” loop of step 442 process the next room on its sorted list. In step443Y, the process of attempting to migrate the given room to anotherplace in the hierarchy tree or to create a new domain and/or newnon-catch-all topic nodes for it is begun. Because the room has a fairlylarge user population, the room will have inherited its own averagedCpCCp and/or averaged DsCCp from the profiles of its individual users.In step 444, the room's averaged profile(s) is/are submitted to a Lookupservice (e.g., a DLUX module) so that the DLUX can automaticallygenerate a proposed location in topic space (e.g., 600) based on thoseaveraged profiles). Alternatively or additionally, the trended topicclustering within the room is used to automatically generate one or moreproposals of where the room should be migrated to next. The trendedtopic clustering data may show a location in topic space where the roomhas historically concentrated and a location in topic space where theroom's recent activity is trending towards. If the room's averaged topicclustering data and/or averaged CpCCp and/or averaged DsCCp closelycorrelate with one or more pre-existing and non-catch-all nodes alreadyin the system hierarchy tree, then the Lookup service(s) will find thosenodes in step 444 and sort them according to which found node isprobably the best match for the room's inhabitants. These found nodeswill constitute automatically generated destination proposals which theroom's inhabitants can vote on. In one embodiment, users within arelatively large catch-all room are automatically clustered (see FIG.5A) into smaller groups of more closely co-compatible users based onpersonality co-compatibility and/or other forms of co-compatibility(e.g., narrowness of topic, topic proficiency preferences, etc.). Forthe one embodiment, these small groups of personality-wise, closelyclustered users (not to be confused with topic clustering) areautomatically offered the option of cleaving out of the large catch-allinto their own, topic-specific and/or personality clustered online room.If a prespecified portion of the clustered mini-group of personalityco-compatible users agree, then lookup step 444 bifurcates itself toserve the agreeing mini group as well as separately serving thenon-agreeing others in the to-be-migrated catch-all room. The migrationpossibilities offered for voting upon to the agreeing mini group may bebased on mini group statistics rather than on statistics (e.g., trendedtopic clustering data) of the whole room.

Step 445 tests to see if the automated look up process looking fordestination nodes to propose was successful. If No, because there is nopre-existing node in the system hierarchy tree that already closelymatches with the room's topic, control passes to step 445N and a newdomain and/or new topic name plus its specification (different fromthose pre-existing in the system hierarchy tree) are automaticallyproposed based on data found in the room's profile(s) and/or the moredominant terms found in the room's recent transcript. For example, ifthe room profiles are very wide in scope and everyone in the room istalking about “HH” (where the system searches back to learn that HH isshorthand for Harry the Hairdresser, and the pre-existing nodes in thesystem hierarchy tree do not include ones directed to HH; then theautomatically generated proposal may be one for creating a new domainnamed “Harry the Hairdresser”. Later, rooms under this new domain willbreak off into separate topic and sub-topic nodes as groups break off todiscuss different aspects of the HH phenomenon and the tree structurefurther evolves.

On the other hand, if the look up in step 444 produced one or morefinds, then step 445 passes control to step 445Y (Yes) and the foundnodes are posted as proposed and to-be-voted-on locations to migrate thecurrent room to, with the highest scored find being listed first. In oneembodiment, the proposal that is generated by step 445N (No) is appendedto the bottom of the list produced by step 445Y so that users of theto-be-migrated room have the 445(N) result as another option to vote on.

In step 446, the automatically generated migration proposals of steps445Y and/or 445N are submitted to the room's eligible voters orlegislators to vote on and optionally debate over before casting finalvotes. In one embodiment, step 446 a allows eligible ones of the room'susers to debate, propose amendments, propose new migration targets, etc.The eligible users may be a predetermined subset of the room's usercommunity or all of the then active members. The room may havepreexisting quorum requirements. (If the quorum requirement is not metwithin a predetermined time, the thread jumps to step 447N.) after apredetermined debating time (if any) elapses, control passes to step 446b where the migration proposals are finalized and put out for voteaccording to the room's predefined voting procedure (e.g., majoritywins, revote on the top three, etc.). In one embodiment, the to-be votedon destination locations are displayed to eligible-to-vote users in atopic space format such as the polar coordinates one of FIG. 6.

Test step 447 determines whether any proposal won and if so whether witha sufficient number of votes to justify migration. If No, next step 447Ndetermines if there are any further room's on the list generated by step442, and if Yes, it passes control to step 443 for processing the nextroom on the sorted list. If No, control is passed to step 443N(described above).

If test step 447 results in a Yes, control passes to step 447Y whereinthe current room is migrated to a new node in accordance with thewinning proposal. If the proposal was to simply move the room to apre-existing non-catch-all node in the hierarchy tree, then this is doneand information regarding the move is broadcast at least to the datacenter DLUX modules and also recorded in the data center GSDS (e.g., 431of FIG. 4A). Later the move information is spread to other data centerswhen bandwidth permits. Part of a migration vote and move may includevoting on and changing the name of the room and/or its specifications.If the winning proposal was to create a new domain node and then attachthe current room to that new domain node (e.g., the “Harry theHairdresser” domain) then this is done where the vote results dictate(to the extent allowed by system policies) the name of the new domainnode (see 451, 452 of FIG. 4B) and the specification of the new domainnode (see 453 of FIG. 4B). The room profiles may provide data forautomatically filling in the common URL's list (454), common keywordslist (455 a), common meta-tags list (455 b) of the new domain node.Alternatively or additionally, the room's voters who voted to create thenew domain node may have an explicit say in how the common lists (e.g.,454, 455 a, 455 b) are filled in.

After the given catch-all chat room has been migrated to a newly-createddomain or to a newly-created node or to a pre-existing node by step447Y, control over the room migrating system resources is passed to step448. Here, a system resources scheduler determines how much bandwidth isavailable for continuing to perform room migration operations. Ifresources are currently in short supply (tight), then the scheduler ofstep 448 may decide to restrict the background rooms migrator to movingcatch-all rooms only out of the catch-all domain of the system'shierarchy tree to some other domain and/or a topic node immediatelyunder the domain node but not to a more refined position in thehierarchy tree. Refinement can take place at a later time when moreresources are available. In that case control is next transferred toentry point 441 a. Step 441 is repeated with the node pointer pointingat the root node.

On the other hand, if bandwidth constraints are mild (medium), thesystem resources scheduler of step 448 may decide to instead next passcontrol to step 443N. Under this pathway, one or more catch-all rooms ofa pre-existing named domain node will be processed. On the other hand,if bandwidth constraints are substantially nonexistent (large, wideopen), the system resources scheduler of step 448 may decide to insteadnext pass control to step 449. Under this pathway, the node pointercrawls through deeper, lower level nodes of the hierarchy tree below thelevel of the root's catch-all domain or the catch-all rooms of thehighest level named domains. Once the pointer of step 449 is set topoint to a lower level node (assigned on round robin or other fairdistribution basis), control is passed to entry path 441 b and fromthere into step 441. It is to be noted here that, in one embodiment,catch-all rooms come in different flavors. A catch-all room is one wherethe room's predominant domain and/or topic are not yet resolved and theroom's participants are jumping around many topics without yet havingsettled their focus on one room-defining topic. However, just becausethe room's basic topic has not yet been defined, that does not mean thatparticipants in the room necessarily are focused upon entirely differentcontent items. They could be focused upon same or similar content items(e.g., a same URL) and yet be associating different topics in theirminds to the same or similar content. By contrast, there can be othercatch-all rooms where the participants are not focused upon any contentat all or are focused upon substantially dissimilar items of content(e.g., unrelated URL's) and these participants have gotten together in achat room simply because they like to talk to each other about nothingin particular. More specifically, the match-making system has clusteredthem into a no-common-focus room simply because their personalityco-compatibilities are very strong (e.g., scored above a systempredefined threshold). At some later point in time, users in any ofthese different kinds of chat rooms can vote to define a predominantdomain and/or topic for their room and to migrate the room to anothernode in the data center's hierarchy tree or they can abandon the roomand leave it to the system garbage collection services to automaticallydissolve the room (and perhaps a temporary node under which it wassponsored). So to summarize, catch-all rooms may be ones whose users arefocused upon a same item of content (e.g., same URL) or focused uponsubstantially similar items of content (e.g., different news reportingsites but directed to same news story) or not focused upon anyinterrelated content at all. The system may automatically identify thesedifferent kinds of catch-all rooms and maintain respective differentvote and migration managing rules for managing votes and migrationproposals made in the respective the different kinds of catch-all rooms.

Even after a catch-all chat room has been initially named and placed ata non-catch-all node, it's position in the hierarchy tree and/or itscharacteristics may not remain static and the same. Rooms have atendency to evolve. As mentioned, users may enter and leave at varioustime points and by doing so change the averaged attributes of the room,particularly if it is a lightly populated room. While users areparticipating in a given chat room and voting, the system mayautomatically put up for a vote by the chat room participants, theDomain and topic names which the users think best describes the currentchat. If a sufficiently large vote is received (in accordance withsystem defined rules for vote taking in that room), the system willreassign the room to the new Domain and topic, for example by amachine-implemented automated process such as that of step 443Y to step447Y of FIG. 4D. Additionally votes from users in a chat room may beused to create room-validated Domain proficiency level values for theDsCCp's of users in the room who ask for their DsCCp's to be voted on byother room members. Domain and topic proficiencies may be furtherestablished by nontransparent displeasure votes cast by users(explicitly or implicitly) against other user in the chat room. Forexample if a voting user repeatedly expresses that they don't want tochat with certain other people because those other people have lowproficiency for this Domain and/or topic or that their personality isdispleasing, then that information about relative levels of proficiencycan be used to increment up or down the proficiency scores in theDsCCp's of the voting users and the voted against users and thusnormalize the proficiency scores given to the DsCCp proficiency scoresand/or preferences of users in a given domain and topic room. Similarlyvotes regarding personality co-compatibility will be used to establishreputations in corresponding CpCC profiles. In one embodiment, thetrending behavior store 437 of each data center keeps track ofbehavioral trends exhibited by users assigned to that data center. If aparticular user normally does not cast negative votes and then one dayit is observed she is casting negative votes against everyone else, theUAS 412 may automatically determine that the given user is having anunusually bad or off day and may then delete or discount votes cast thatday by that given user.

The categorization location within a data center hierarchy tree (e.g.,401 of FIG. 4B) of a particular Domain/topic/subtopic node relative toother Domains/topics nodes with similar common CFi match values (e.g.,464, 465 a, 465 b, etc.) may be used to automatically create “relatedDomain/topic nodes” lists (e.g., distant relatives, see 468 of FIG. 4B)that can then be automatically published as in-box invitations (316 c ofFIG. 3A) in current chat windows displayed on respective client machines440. Thus, if a given user is chatting in a first such room (e.g., 316b) and sees the list (316 c) of related Domain/topics scroll by, theuser may elect to migrate to one or more of the other chat rooms (316 c)because the user feels the corresponding Domain/topics specified forthose one or more other rooms are more suitable to the user's currentinterest. In one embodiment, the system may automatically keep track ofhow many users elect to accept this switch over option and to switchfrom a first given room (316 b) to a second alternate room (in scrollinglist 316 c). For example if a large percentage of users who initiallyaccept an invitation to enter a first chat room sponsored under theDomainA/TopicB node quickly accept switch over to a co-related secondroom sponsored under the DomainC/TopicD node (where A, B, C, D aredifferent identifiers here), then it may be automatically determinedfrom such in-mass switchovers by users that that the CFi hint valuesand/or knowledge-base rules used to initially match the switching overusers to, and invite them into the DomainA/TopicB room should instead beused to automatically match them to the more preferred DomainC/TopicDnode. The system adaptively alters its match service heuristicsaccordingly. For example, the system uses expert system patterndiscovery services running in the background to discover whatdiscernable pattern of attributes classifies certain users as preferringthe room under the DomainC/TopicD node as opposed to the initiallyentered room under the DomainA/TopicB node. Thus the system canprogressively improve its match making abilities based on user migrationbehavior.

In one embodiment, users who are displeased with having been invitedinto the DomainA/TopicB room of the above example and who do not see analternate acceptable room being automatically published as an in-boxinvitation (316 c of FIG. 3A) in current chat window are given anone-of-the-above vote option. By picking this option, they indicate tothe system that they fervently do want to now chat about their focusedupon current content, that none of the system-suggested domains and/ortopics match what is currently in their minds, and therefore that thesystem should spawn a new domain and/or topic for association with thegiven content they are focusing upon. In response, the systemautomatically clusters the plural users (where their number has to beabove a system predefined threshold) who picked the none-of-the-aboveoption into a new catch-all room (of the kind that does have usersfocused upon common content) and the system initiates a vote processwhere the room users can propose new specifications for the room'sdomain and/or topic and vote upon the same. If predefined system voterequirements are met, the system automatically creates a new topic node(or even a new domain node, if enough people want such) corresponding tothe desires of the winning voters in the none-of-the-above option roomand migrates the room (and its participants of course) to the newlycreated node.

Referring to the specifics of FIG. 4B, one possible hierarchicalorganizing system 401 (as defined by stored data in a corresponding datacenter) is shown to include a global domains root 402 for its respectivedata center number, N. Each data center 410, 420, etc. will have its ownroot. Each root will having uniquely identified (e.g., numericallymarked) branches 405, 407, etc. leading to respective domain level nodes450, 470, etc. In one embodiment, the unique branch identifiers) ofbranches 405, 407, etc. correspond directly to or map through a datacenter lookup table (LUT, not shown) to the navigation type meta-tagsthat are usable in online content (e.g., as 317 a of FIG. 3A) fordetermining topics of interest. Thus a corresponding meta-tag codeprovided in a user's uploaded CFi data (e.g., 118 a of FIG. 1A) can beused by the matching service 150 c of a given data center to hint at ordirectly address a corresponding node in the data center's domainsconfiguration store 435 when performing a topic match.

Topic nodes and node-to-node interconnect branches in the hierarchicalorganizing system 401 of FIG. 4B may be represented by appropriatedigital data objects stored in the data center hierarchy configurationstore (e.g., 435 of FIG. 4A). Each topic node representing data objectsuch as 450, at minimum is a data structure that is addressable by oneor more system computers for data read and write operations and theobject provides logical links (e.g., direct or indirect pointers) toon-topic information resources where at least one topic that theseon-topic resources cover is a topic associated with the given topicnode. The on-topic resources may comprise on-topic real time chat rooms(e.g., pointed to by pointers 459 of node 450) and/or on-topic referencematerials (e.g., pointed to by pointers 459X) where the latter referencematerials may be the ones recommended as further research materials ormeeting proposals by a matrix like the research materials recommendationmatrix 355 of FIG. 3B for example. Node-to-node interconnections betweenparent and child topic nodes may be provided by pointer data (e.g., 457)embedded in the topic node representing data object and/or in separatedata objects that define parentn-child relations between nodes.

The on-topic information resources (e.g., those pointed to by pointers459, 459X of node 450) of each given topic node (e.g., 450) are notnecessarily fixedly bound to the given topic node and are notnecessarily dedicated to the topic node on a one-for-one basis. A chatroom may migrate from one topic node to another as the topic currentlydiscussed in the room changes. A chat room (e.g., 469 a of node 460) mayhave more than one topic node pointing to it at the same time, forexample because two topics are being simultaneously discussed in theroom. (See for example, pointer 499 to room 469 a which pointer comesfrom another node beyond node 460.) Migration of a chat room from onenode to the next may occur as a Tarzan™-like swinging from one tree vineto the next with room first logically linking to a new next node beforereleasing linkage to an older but now less on-topic node (in so far asthe room is concerned). Just as chat rooms are not necessarily unique tothe topic being discussed in them (in other words, there can be multiplerooms per topic) and rooms can migrate about the hierarchy tree and/orin topic space, the same is roughly true of topic nodes. No one topicnode necessarily has a monopoly on a corresponding topic because therespective topics of nodes can drift and two or more nodes may driftfrom spaced apart positions towards a same spot in topic space. Thetopic of a node is primarily governed by the topic being focused upon inthe majority, mean or median of the node's chat rooms (or other alikereal time forums). So if the mainstream discussions in the node's roomsdrift toward a deviated topic without the mainstream rooms themselvesmigrating away, then the node as a whole should migrate to a new spot intopic space and optionally to a new spot in the system hierarchy tree.Stated otherwise, a given topic node (e.g., 460) is not necessarilyfixedly bound to a specific position in the hierarchy tree 401 and maymigrate to a new position in the hierarchy tree (e.g., under a differentparent node and/or over different children) and/or may fuse with one ormore other drifting nodes and/or may split apart into two divergingnodes, where such changes in hierarchy tree position may be voted for byeligible voters in the system or such changes in hierarchy treerelationships may be made by system administrators and/or such changesin hierarchy tree position may be performed automatically as anautomated trending analysis service realizes that the node's cumulativeattributes (as determined by modules 380, 390 of FIG. 3C; describedbelow) has drifted significantly out of correlation with cumulativeattributes of its parent node and more into line with those of adifferent, next-to-be parent node.

When a given topic node migrates to a new position in its hierarchytree, or fuses with another node, or bifurcates into two spaced apartnodes, the on-topic information resources to which that moved node ornode part currently links may be viewed as inherently moving with thatnode to the new position in the hierarchy tree (and/or to the newposition in topic space). In one embodiment, all current participants ineach room that moved because its node moved are briefly informed thattheir room has shuttled or warped to a new position in tree space or intopic space. After the node move and/or node bifurcation, some or all ofthe chat rooms or other resources logically linked to that moved node ornode part may migrate away on their own or decay away from the movednode. When the latter happens, in one embodiment, all currentparticipants in each room that moved are briefly informed that theirroom has shuttled or warped to a new position in tree space or in topicspace. Thus from the point of view of users inside a room, there is noapparent difference between their room shuttling to a different node orthe node itself migrating to a new place. By way of analogy, each chatroom may be viewed as a kind of space ship that orbits its current nodeplanet (or moon) where the space ship can shuttle off on its own to anew position in tree space or topic space or the planet (or moon) aboutwhich it orbits can change location. In one embodiment, when rooms aredisplayed as graphic on-screen icons, they are displayed as space shipsorbiting a topic node planet (or moon) so as to give users a graphicalsense of where they are in topic space, where nearby space ships are,where nearby planets or moons are, and so forth. (In thisrooms-as-space-ships metaphoric world, the central star in the currentsolar system represents the catch-all domain of a given topic space andspace ships can warp over to other solar systems to thereby placethemselves in alternate topic spaces.) It is to be observed that just asspace ships are not permanent fixtures of the planet they orbit,pointed-to on-topic information resources such as chat rooms (459) andon-topic reference materials (459X) are generally not part of thehierarchy tree node to which they current link. Rather the logicallinkage is a temporary gravitational kind and the pointed-to on-topicinformation resources may be simultaneously pointed-to by multiple nodesand/or may drift in topic space (or tree space) so as to be seen asbeing under the gravitational influence of different nodes at differenttimes. While knowledge of where in topic space (or tree space) one'scurrent chat room is, may not seem to be of importance to all roomusers, it may be so to those who wish to take advantage ofnon-auto-pilot browsing through nearby space and to see and exploremanually on their own what is happening inside a nearby other spaceship(a.k.a. a nearby other room; if let in upon requesting) or what ishappening in nearby orbits of the current planetary node, and so forth.

Because the on-topic information resources (e.g., chat rooms, like 469a-469N of node 460) are logically linked to, by way of the topic nodes(e.g., 460) of the hierarchy tree, the topic nodes may be viewed notonly as orbit-supporting planets but also as airport terminals (or moreaccurately, spaceport terminals) or as pass-through portals throughwhich users of the system pass (or gravitationally touch upon) when theusers are on their way to accessing the on-topic information resources(e.g., inside the chat rooms). The topic nodes may also be viewed asclustering centers around which plural users gravitationally cluster asthey access the on-topic information resources that are currently ofinterest to them and happen to be orbiting around that specific node. Inactuality, users themselves do not, of course, pass-through such portalsor cluster around them. Rather the resource accessing processes (e.g.,topic lookup computer programs) that provide the respective users withaccess to the on-topic information resources (e.g., to the chat rooms;or offer invitations to the rooms) interact with the topic node dataobjects (directly or indirectly) in such a way that the interaction canbe analogized to having some users passing through, temporarily orbitingaround, or clustering around the nodes. One of the interactions thatwarrant such analogy can be that of bringing personal baggage to thecorresponding spaceport (to the specific topic node object). When thishappens, spaceport authorities (actually modules servicing the node,such as 380, 390 discussed below) can insist on taking a sampling of therelatively current CFi data that was brought along or used by the userto get the user to that topic node because it was determined (e.g.,because a DLUX, e.g., 362 of FIG. 3C determined) that the user is moreprobably than not, focused upon the topic of that topic node. Thesampled CFi data can include a URL of a web page that the user wasstrongly focusing upon just before he or she was brought to that topicnode. If enough passing through one of the users who touch upon the nodehave CFi data with the same URL, the system automatically correlatesthat commonly referenced URL (commonly referenced now) to the currenttopic of the given topic node. Such a URL can become one of so-calledcommon URL hints (454 in FIG. 4B) of the topic node, as will be detailedbelow. If certain passing through users with strong credentials and/orreputations (e.g., validated or licensed) in the topic of the giventopic node come with special, uncommon URL hints embedded in their CFidata (uncommon to the lay public, but common to the credentialedexperts), the system automatically correlates those special URL's asbeing expert level hints pointing to the current topic of the giventopic node. This is just an illustrative sampling of what can be donewith the various pieces of data that passing through users bring withthem as they pass through the portal-like topic node. Besides uploadedCFi data, passing through users can bring with them to the node whosetopic is of current interest, their respective current CpCC profilesand/or current DsCC profiles; where the latter contain data that can beautomatically correlated to the current topic of the given topic node.Besides uploaded CFi data and the carry-along baggage of CpCCp and DsCCpcurrent profiles, passing through users may provide votes about thecurrent topic and/or hierarchy placement of the topic node orsuggestions for the topic node. For example, a highly credentialedexpert in the current topic of the topic node may, when passing through;provide a suggestion that a subtle change be made to the specification(452, to be discussed) of what the current topic of the node is. Thispassed along suggestion can be automatically brought up for a vote byother voters eligible to vote on the fate of the topic node. (Where thatfate incidentally, is not necessarily the same as the fate of a givenchat room currently running under that topic node. The fate of each chatroom can also be brought up for vote by eligible voters of the room,where the fate may include migration to a different topic node).

Aside from having a hierarchical position in the hierarchy tree 401, oneor more of the topic nodes (but not necessarily all) can havedata-defined positions in a prespecified topic space 600 such as, forexample, sub-topic node ST1.45 (FIG. 6) being positioned within a topicshadow cone 601 (which cone is determined by sweep angle definingparameters of the node) of domain node D1 in FIG. 6. Positions in topicspace of the given topic nodes can change based on user activity orvotes. Positions in topic space may change even though a given noderemains hierarchically anchored to a same parent node while the child'stopic space position shifts. This can happen for example if the parentnode changes position in the topic space or the child node changesangular position in the topic space. As with hierarchy position, topicspace position can be changed in response to votes of usersparticipating in chat rooms of the given node. Topic space position canrepresent inter-node relations other than those represented merely byparentn-child hierarchy relations in the hierarchy tree. For example,topic nodes that are within a specified arc swing of each other and/orwithin a specified radial distance from each other in a given topicspace may be deemed to have special relations such as closelyinter-related topics. If one topic node in the outer reaches of topicspace (far way from solar system center D0 in FIG. 6) is under-populatedby chat room occupants and there is another topic node closer to thecenter of topic space and also lightly populated, where the two topicnodes are roughly along a same radial line or within a same shadow coneof acute angle (e.g., cone 602, whose vertex is at the origin), thesystem may automatically move the nearly empty chat rooms of the outernode to the inner node and then merge co-compatible ones of the roomsthat now attach to the inner node. This is an example of how topic spacemay be used. In one embodiment, topic space coordinates (e.g., polarcoordinates) of a given topic node (e.g., node 450′ of FIG. 3C) arestored as part of the topic node object (e.g., in region 450 pc of FIG.3C).

Still referring to FIG. 4B and more specifically to the firstroot-to-node connecting branch 405 of FIG. 4B, it is noted that thisexemplary branch is uniquely identified by the global domain tag number:“001” (which number is encoded in the data object or object portionrepresenting branch 405). As a result, the first topic node 450 at theend of this first branch 405 may be navigated to from the root node 401by specifying connecting branch 405 having global domain tag number:“001”. The first exemplary node 450 is assigned a dynamically changeableprimary topic or domain name 451 either by users or by the systemadministrator. Examples of primary domain names may include: News,Entertainment, Health, and so forth. Some users may prefer an alternateor alias name and the illustrated system allows for such alternativenaming of domain or topic nodes by means of alias name entries like thatof memory area 452. The name given to a domain may not fully explain itscorresponding mission and/or what topic topics are to be included or notunder the shadow of that domain. Accordingly, in one embodiment acovered-topic(s) specification record 453 (e.g., a database record orfield therein) is logically attached to the domain node object 450 tobetter define its mission statement and/or what topic or topics areintended to fall under that dynamically re-namable domain node 450. Inone embodiment, users in chat rooms currently attached to the node mayvote on what constitutes an acceptable specification 453 for the givendomain node or the system administrator may fix such a nodespecification 453. In one embodiment, essentially all attributes of eachdomain or topic node including for example, topic name (451), topicspecification (452), node parent name, node location in topic space (see450 c of FIG. 3C), node URL or other hints, etc., are stored as keywordsearchable fields in a relational database so machine-implementedsearches can be made for example, for all topic nodes currently having atopic space radius of R1 (a supplied radius value) and having a topicnode name including the word “soccer” and having a topic nodespecification including the word “judge” or “referee”. This of coursemerely being an example. Although not shown in FIG. 4B, each topic node(e.g., 450, 460, etc.) may additionally have routine directoryattributes stored for it such as, but not limited to: date and time ofnode creation, date and time of last modification, date and time of lastaccess (by a system administrator), access permission, amount of datastorage space consumed for specifying the node, number of hits perminute by DLUX services referencing the node, and so on. Accordingly,database searches may query for all nodes newly created in a certaintime range and having a hits rate exceeding a specified thresholdnumber.

When uploaded CFi's are received from different client machines and thedomain/topic lookup process (DLUX) determines that these CFi's hint at agiven topic node such as 450, the system looks for those of thecorresponding CFi's that include URLs as their topic hints. Statisticalanalysis of incoming CFi's may indicate that some URL hints (or othercontent address identifiers) are currently more popular or common thanothers for pointing to a given domain node (e.g., 450). Other analysisof incoming CFi's may indicate that credentialed experts in the currenttopic of the given topic node favor a particular subset of URL's whenapparently having the topic of the given topic node currently on theirminds. In one embodiment, these more commonly seen URL hints are storedin logically attached, URL hints record 454. The expert-preferred URL'smay be similarly copied into another hints record (not shown) like 454.These more commonly seen URL hints (or other address hints) and/or theexpert preferred URL hints (or other address hints) may be automaticallycopied into template DsCCp records and/or into user's DsCCp rules set(see 195 of FIG. 1C) so that the same information can be communicated toresource users when they review their own DsCCp's and thus they canlearn about which URL's are most commonly used by lay people and/orcredentialed experts for a given topic of interest. In one embodiment,the domain lookup service (DLUX, discussed below) consults with thecommon URL hints record 454 (and optionally with the experts' pick URLhints record) of each domain or topic node as well as with the user'sDsCCp to determine whether there is a probable match between the topicof current interest on the user's mind and the corresponding topic node450. If yes, a corresponding match request may be generated for handlingby a domain or topic specific match service (DsMS) to match the userwith a personality or otherwise co-compatible chat room. A similarscheme may apply to commonly used keywords found within the CFi's of layusers and/or topic experts as indicated by attached keywords record 455a. A similar scheme may apply to commonly used meta-tags (other thanspecial hierarchy navigation tags) within the CFi's of lay users and/ortopic experts as indicated by attached meta-tags record 455 b. Ellipses456 indicate that yet further hinting mechanisms may be similarlyattached to the corresponding domain node 450. If the domain lookupservice automatically determines that there is a sufficiently strongmatch of interest for just that domain node 450 and none of itschildren, the domain lookup service (DLUX 415 of FIG. 4A) will forwardthe found user-to-domain association to a corresponding domain matchservice (e.g., 416 of FIG. 4A). Once the DsMS 416 finds or creates aco-compatible chat room (see room 469 a of node 460), the DsMS willgenerate an invitation to one of the chat rooms pointed to directly orindirectly by the node's room pointers 459. In one embodiment, eachdomain and/or topic node has just one primary rooms pointer like 459which points to a database record (e.g., to an expandable linked list)containing pointers to corresponding chat rooms that are currentlyassociated with the topic of the node 450. The pointed to chat rooms maybe hosted in the local data center or in a remote data center. Chatrooms are not permanently married to the topic nodes which point tothose chat rooms. As mentioned above, the main topic or topics ofdiscussion within a given room may change over time and as a result, thechat room may become de-linked from a first topic node (e.g., 450) andre-linked to one or more new topic nodes (e.g., 460, 480). Also, thetopic name and/or topic specification of a given topic node may changefrom time to time; in which case, some rooms may elect to migrate awayfrom that node and others may elect to migrate toward that node.Additionally, it is to be understood that although a given node such as450 may point directly or indirectly to a large number of chat roomsthat are taken to be substantially on-topic relative to the currenttopic of the given topic node, not all of these rooms will necessarilymeet the co-compatibility preferences of the then-being-serviced userwhich is why the DLUX service 415 hands off the job of filtering forrooms that are not only on-topic but also have chat co-compatibilitywith the then-being-serviced user to one of the DsMS services 416.Accordingly, the CpCCp and/or DsCCp's of the then-being-serviced userwill be consulted to narrow down the list of chat rooms to which theuser will be invited (if at all; if the measured co-compatibility scoreis high enough). Finally if the filtered down list of co-compatiblerooms is too long (exceeds a predefined target value), a randomlyselected subset of the list may be used to generate invitations that areactually sent to the then being serviced user via the Cciv's (e.g., 118c of FIG. 1A). In one embodiment, data is stored to indicate thatrespective chat rooms have their own personality and/or topicproficiency profiles (CpCCp's and DsCCp's) as inherited from anaveraging of the room's current participants and/or as voted on by thecurrent participants. The room's profiles may be used to developdistancing vectors (see 562 of FIG. 5A) between the room and potentialnew users. These distancing vectors may operate to automatically keepout from the room newcomers who are objectionable to the room's currentoccupiers.

While examples given herein have mostly focused on users who are to meetonline, it is also within the contemplation of the disclosure to haveusers meet in person with the aid of the match-making system. Consider afirst user who happens to be at a large business convention; sayMacWorld™ in San Francisco where hundreds of Apple Macintosh™ devoteesmeet annually. Let's say that professionally, this first user is anexpert in Java scripting algorithms as used on the Macintosh™. However,at the current moment he is not interested in talking more aboutMacintosh™ Java scripting. He is all talked out about that topic. Hisuploaded CFi's of the last two hours show that he is currentlyinterested in talking about vacationing in the Bahamas; and morespecifically, which hotels there are best. Unbeknownst to the firstuser, there is a second user also attending the MacWorld™ convention.The fact that both users are concurrently at MacWorld™ is indicated bytheir recently uploaded CFi data, both showing GPS determinedpositionings in the Moscone Convention Center in San Francisco. Thesecond user's recently uploaded CFi's of the last few hours show that hetoo is current interested in the topic of good hotels in the Bahamas. Inone embodiment, the system invites the first and second users to a chatroom whose current topics of interest are the MacWorld™ convention andhotels in the Bahamas; with emphasis (more weighting) being placed onthe latter. In one embodiment, the system also automatically mentions inthe invitation that the other user happens to be physically at theMacWorld™ convention and appears to be co-compatible chat wise (and moreparticularly for in person chats) with the invited user. The two usersmay then negotiate online to meet in person at the MacWorld™ convention;not for the purpose of talking about Macintosh™ Java scripting, butinstead to talk about best vacation hotels in the Bahamas. With theirjoint agreement, the system may then automatically flash the photographof the other user, his CV or resume to the portable client machine ofeach user and use uploaded GPS data (from their cell phones) to indicatehow far apart they are and in what direction. In this way, two relativestrangers at a large business convention may be brought together to chatabout a topic of current interest, even one having little to do with thebusiness convention. If they form a strong friendship bond over thefirst topic (e.g., Bahamas), they may later move on to other topics ofmutual interest. This was an example of how currently uploaded GPSpositions in combination with hints about topic of current interest canbe used to automatically bring together people who might not haveotherwise gotten together despite having many topics of current interestin common.

With regard to invitations (e.g., the Cciv's 118 c of FIG. 1A), it is tobe understood from the above that each Current Chat Invitation (Cciv)may provide information serving as a recommendation for a particularchat room or for another user-to-user real time exchange or for a nonreal-time interchange (e.g., blog) that a user might want to join basedon inferences made by the match-making services in the cloud regardinglikelihood of sameness or similarity in current topic of focus,likelihood of personal co-compatibility with other chatters in the roomor with the room in general and/or likelihood of desired levels ofproficiency by the user and/or by other chatters in the room withrespect to one or more topics. In other words, although much of theabove disclosure has focused on indexing real time chat rooms undertopic nodes of a system hierarchy tree, it is within the contemplationof the disclosure to index non-real time online destinations orin-person meeting proposals under topic nodes of a system hierarchy treeand to automatically infer one or more topics of current interest of aclient user based on recent content that was focused upon by that userand to then automatically suggest to the user (e.g., by providing ahyperlink to the suggested online destination, where such suggestion isa broadened form of invitation) that the user may want to link to thesuggested online destination (e.g., an online blog, and online tweetstream, online proposal for an in-person meeting, etc.) In oneembodiment, both real time chat rooms and non-real-time or off-lineexchanges such as blogs, list-serves, etc., are stored under nodes of asystem hierarchy tree and the tree's configuration (e.g., hierarchicalorganization of nodes) is controlled by votes cast from the chat rooms.Thus a living hierarchy tree is formed that can change its configurationin substantially real time in response to current votes of online chatroom users and the topic nodes of the tree can point not only to chatrooms that are currently on-topic, but also to non-real-time on-topicexchanges such as blogs or meeting proposals and even to static contentproviding web pages associated with the node topic. In one embodiment,vote-eligible participants of chat rooms running under a given topicnode are empowered to recommend or de-recommend and vote onnon-real-time on-topic exchanges and/or on-topic static contentproviding web pages that the tree node will point to. The on-topicpointers to nonn-chatroom content may point or otherwise logically linkto a variety of nonn-chatroom content including, but not limited to:on-topic videos (e.g., recent YouTube™ clips), on-topic books, on-topicmovies, on-topic TV shows or online shows, on-topic shopping lists orlists of vendors that service the public with items related to the nodetopic and so on. When one or more chat rooms depart from the node (dueto migration to at least topic or loss of participants), thecharacteristics of the node automatically change (e.g., at prescribedcheckpoint times). These automated changes can include changes to thenonn-chatroom content pointed to by the node.

The recommendation information provided by each Cciv may include: (a)Summary data about the chat room or about nonn-chatroom material thatcan help the user decide whether to join the chat room at this timeand/or open the associated nonn-chatroom material (e.g., the summary canprovide the current name of the topic node, the name of the chat room, adescription of the room topic, a summary about moderator or leadcontributors, etc.); and (b) The data needed to enter that chat room(i.e. the identity of the CRS resource hosting that room, identity ofthe hierarchy location of the to-be-joined chat room (i.e.,domain/topic/subtopic/etc.)), (c) An indication of whether it is a newroom being now created, etc. and if so number of other users expected tojoin. The cloud may provide this or various other forms of recommendingdata as may be indicated to be desired by the user population. Automatedmeans for adapting to the informational desires of the user populationmay be incorporated in the cloud as well as means for delivering thedesired information for determining whether or not to join a chat roomor other user-to-user real time exchange or to open the associatednonn-chatroom material (e.g., non real-time interchange such as blog,tweet, list serve, etc.).

When a DsMS takes on new chat rooms as being covered by, for example anew hierarchy node added under the hierarchy tree region managed by theDsMS, the DsMS performs an inventory collection run regarding its newlyacquired node and underlying rooms by querying the responsible CRS's(418). This inventory collection run may include querying the CRS'shandling the new rooms and obtaining from the CRS's answers to questionssuch as: (a) Current Status of the chat room, i.e., open and running orempty and not running; (b) List of open chat rooms under the managementof the given CRS; (c) Counts of participating members in each of therunning (active) chat rooms; (d) Details regarding the members in eachchat room; and (e) Average number of transactions per second or othertime unit for each of the active chat rooms under the management of thegiven CRS. The DsMS can use this collected information to manage andredistribute its workload as necessary. For example, if a newly acquiredgroup of chat rooms is very busy and corresponding co-compatibilityscoring and sorting for members of the newly acquired group of chatrooms will probably overload the DsMS, the DsMS can contact itssupervising DLUX or AARMS and request reassignment of part of the chatrooms covered by the given DsMS to another DsMS. An example of when aDsMS may be forced to take on a newly acquired group of chat rooms iswhen those chat rooms are initially designated as catch-all rooms butthen the system recategorizes them as belonging under a pre-existing ornew topic node managed by the given DsMS.

Each domain node in the hierarchy, such as node 450 may have one or morechild nodes logically attached thereto as indicated by the immediatechild pointers shown at 457. This is mostly conceptual. In oneembodiment, there is just one immediate child pointer at 457 pointing toan expandable linked list of pointers which then point to the childnodes. In this way, the number of child nodes can be more easilyexpanded or contracted as appropriate for current system conditions. Inthe same or another embodiment, each child node has a pointer (notshown) pointing back to its immediate parent node. This allows eachparent node to have a highly variable number of immediate children.

Each of the child pointers (e.g., 457 a) in FIG. 4B is uniquelyidentified (e.g., numerically marked) such as by the illustrated “0.01”identifier and it points to corresponding child node 460. If a pulled innavigation type meta-tag (navMeta-Tag) within a user's CFi reads as“001.01” then the domain lookup service (415) may use this parameter toautomatically determine that the CFi is hinting at navigating to domainnode “001” (node 450) and from there to corresponding child node “.01”(node 460). Each child node such as 460 may have a similar datastructure as that of its domain node 450 including having a topicprimary name stored in record area 461, an alias name stored in recordarea 462, a topic definition stored in record area 463, a furtherlogically attached memory region 464 which stores the most commonly usedURLs for referencing that topic 001.01, a further memory region 465 awhich stores the most commonly used keywords for referencing that topic001.01, a further memory region 465 b which stores the most commonlyused meta-tags (other than special hierarchy navigation tags) forreferencing that topic 001.01, and pointers 467 to immediate subtopicchildren of the given topic node 460. In one embodiment, additionalpointers 468 may be provided to point to distant relatives of the giventopic 460. For example other domains or topics that are somehow crossrelated with the given topic node 460. Similarly, each domain node(e.g., 450, 470) may include pointers to distant relatives of that nodesuch as indicated at 458, 478.

As seen in FIG. 4B, the second domain branch 407 (navigation wisemeta-tagged as “002”) and its respective node 470 have similar datastructures, like primary name 471, etc. logically attached to them andfurther topic data structures such as node 480, etc. attached theretoand so on. A complex and logically interlinked hierarchical tree 401 maytherefore be built up in each data center (410, 420) out of these basicstructures. While the illustrated logical links of FIG. 4B are shown asone way links, it is within the contemplation of the disclosure to useindirect pointers to expandable linked lists or database tables or touse reverse-directional links which point back from children to parentsor grandparent nodes as well.

When a match-making service invites a user into given first chat room,the invitation accepting user may discover that the room is not quite tohis or her liking. The reasons can be many and varied. For example, thetopic of interest in the system suggested room is not exactly what theinvited user had in mind. Another possibility is that the personalitiesof the other users in the room are not quite to the invited user'sliking. In one embodiment, an invited or accepting user can invoke a“browse the hierarchy tree” function from his local machine. Inresponse, the match-making system sends back a display of folders andsubfolders representing the nodes of the tree with the contents in thefolders representing that node's chat rooms. (In one embodiment, somepremium nodes may be hidden from nonpremium users.) The displayedhierarchy indicates where the current invitation points to and providesthe user with the ability to manually browse (navigate among) thedisplayed nodes, either horizontally within a given parent folder orvertically up to a higher level parent folder or deeper down into adirect child folder. Additionally the user may navigate (with or withoutthe aid of user-specified filtering constraints e.g., show me only roomsthat have an average age above 35 years old) along the indirectconnection paths offered by the distant relative pointers (e.g., 458 ofFIG. 4B) in search of better matching chat rooms. In other words, afterthe automated match-making system guessed almost correctly regardingwhat the user had in mind and/or regarding the kind of co-compatibleother users the first user wants to converse in real time with, thefirst user can tweak the results by manually navigating in the hierarchytree horizontally and/or up or down along its branches in search of amore suitable chat room that is logically associated to theautomatically suggested chat room (to the one the system invited thefirst user to). Of course, not all nodes will necessarily have activechat rooms. If a node does not have an active chat room, the user mayask the system to invite others to join the user in a chat room underthat node. After a user picks a new node or room better to his liking,asks to be invited into the active chat room, and does get invited intoit (not always guaranteed because some rooms have restrictions), thesystem records the event in a trending history file associated with theuser; and later when bandwidth permits, automatically invokes aknowledge-base patterns discovery service for discerning how that user'sknowledge-base rules sets should be tweaked (if at all) in view of theuser's browse-and-request-invite activities. Thebrowse-and-request-invite option may be provided in combination with theabove described “none of the above” option where multiple users rejectautomated match-making suggestions made by the system. Aside fromdisplaying the nodes as parts of the hierarchy tree, the system maydisplay to an authorized user, the nodes as distributed in a topic spacesuch as that of FIG. 6 and may allow the user to navigate through thetopic space.

Referring momentarily back to FIG. 4A, before the DLUX 415 and DsMSservices 416 of a given data center (410, 420, etc.) process a clientmachine's CFi's as described above, the client machine (e.g., 440 a)should establish a client/primary-server relationship with one of thedata centers. This is done in cooperation with one of the Access andAccessible-Resources Monitoring Services (AARMS) 411, 411′ in one of thedata centers. In one embodiment, each client machine (440 a, 440 b,etc.) is pre-assigned a specific first data center as its primary homecenter and a geographically distant second data center as its backuphome center. The client machine tries to first establish communicationwith its primary home center (e.g., 410), but if that does not succeedfor whatever reason (power outage, etc.), after a predefined number ofretries, the client machine will instead try to establish communicationwith its backup home center (e.g., 420). Irrespective of which homecenter (there could be a tertiary one, etc.) establishes the initiallink, the home center may nonetheless refer the client machine out to aremote data center because resources in the home center are currentlynear an overwhelmed state. Determining whether this is the case is thejob of the home Access and Accessible-Resources Monitoring Service(AARMS) 411 which operates in conjunction with its local ServicesDirectory Store 431. As its name implies, the Global Services DirectoryStore 431 stores loading and availability data about substantially allservices (of substantially all data centers) on at least a regional partof the network if not the whole of the network. For example, the GSDS431 will store information indicating how busy the local DLUX service415 is, about how busy the remote DLUX service 415′ in a nearby datacenter (e.g., 420) is, about how busy yet another remote DLUX service415″ (not shown) in yet another online data center (not shown) is, andso on. The GSDS 431 will store information indicating how busy the localand remote DsMS services (416, 416′, 416″, etc.) are. The GSDS 431 willstore information indicating how busy the local and remote chat roommanaging services (CRS 418, 418′, 418″ etc.) are, where this includeskeeping track of how many users are chatting within each local chat roomand what percentage of the chat room limits this amounts to. With thisinformation, the AARMS 411 can determine whether resource within thelocal data center (e.g., 410) will be able to service a given clientmachine (one that is first logging in or one that is starting to send inCFi's directed to a new domain and/or topic) or whether the clientmachine will be better served by being handed off to a less loaded datacenter (e.g., 420). For example, if the local time for a first datacenter is the middle of a busy business day, then it may be expected tobe under a heavy user load (generally speaking). On the other hand, adata center several time zones away where the local time is 2:00 AM maybe expected to be under a much lighter user load (generally speaking)because most of its primarily assigned home users are asleep. So userstrying to log into a heavily loaded first data center may be handed offby the AARMS (411) of that first center to the AARMS (e.g., 411′) of asecond data center several time zones away. In this way user load isredistributed among data centers so that no data center will generallybecome overloaded by too much traffic.

First of course, a just-turned on client machine should generally log-ininto one of the data centers. This function is handled by the UserAccounts-management Service (UAS) 412. In general The User Accountservice (UAS) facilitates and performs the tasks needed to create newuser accounts, to save changed user profiles (e.g., CpCCp's, DsCCp's,rPEEP's in the local UAS data store 432) and to manage user passwordsand other security measures (e.g., face recognition, voice recognition,etc.). Also, the UAS 412 may manage background synchronization of userrecords across plural data centers so that when a user account record isaltered at one data center, the latest changes are automatically copiedinto other data centers when system bandwidth permits. In oneembodiment, a background running updating service crawls through datacenters during their light usage hours and updates old user records withnewer ones that may have been created or modified in other data centers.The user's account related information is saved in one embodiment to aset of parallel storage devices (i.e. mirrored databases in differentdata centers) in order to facilitate fast data access during heavy usagetraffic loads. Thus if a client machine tries to log into its primaryhome center but the local AARMS 411 flags that the center is not readyto accept this additional client, the AARMS 411 will automaticallyredirect the client machine to another data center which the AARMS 411knows (from data in the local Directory store 431) has a mirror and/ormost recently updated copy of the user's account information. The UAS(e.g., 412′) in that alternate data center processes the user's log-inactivities and then mirror copies the latest account activity into theprimary home center (into data store 432) when network bandwidths allowfor such data mirroring.

Upon logging in through the UAS (412) of a given data center, the AARMS(411) of that center begins collecting CFi (118 a) packets from thelogged-in client machine. The local AARMS (411) determines what rate ofCFi's is being generated by the added on client machine (and/or whatvolume of CFi contained data is being generated per unit of time) andwhether the added on client machine is a premium service user or a userwith lesser service rights. The local AARMS (411) then determineswhether non-premium users should be redirected to other data centers orhave their rate of CFi's servicings curtailed to accommodate the justadded on client machine (e.g., 440 a). Of course, this process repeatsas further client machines (e.g., 440 b, 440 c, etc.) log in and send intheir CFi's. so the AARMS (411) is constantly monitoring usage loads onthe services within its own data center and within sister data centersto determine how resources should be allocated and reallocated astraffic conditions change.

Just because a given client machine has been accepted by a local AARMS(e.g., 411) for servicing of that client machine's CFi's (and Cvi's),that does not mean that the work load from the client machine will behanded off to the local DLUX (domain lookup service) 415. Each localAARMS has it within its discretion to channel parts of its traffic toremote DLUX's (e.g., 415′) rather than to the local one. The localand/or remote DLUX's have it within their discretion to channel parts oftheir respective traffic flows to DsMS's (e.g., 416′) that are remote tothem. Accordingly, when a given client machine is accepted for servicingby the AARMS of a first data center, that does not mean that the DLUX(domain lookup service) in the same data center will necessarily providethe domain lookup functions for all or part of the CFi's originated fromthe given client machine. It also does not mean that one or more of theDsMS (match services) in the same data center will necessarily providethe corresponding chat room co-compatibility matching services. A givenclient machine that links for servicing by a first AARMS (e.g., 411) mayfind itself getting invited into chat rooms being managed by the CRS(418′) of a different data center. This will be particularly true ifthere are no co-compatible chat rooms in the data center of the firstAARMS.

The CRS's (e.g., 418, 418′) in each of the data centers provide typicalchat room support features found in conventional servers that host chatrooms, such as facilitating real time discussions among groups orindividuals and flagging problems out to system administrators.Additionally, the CRS's of the match-making system facilitateuser-to-room activities such as allowing users in the room to makerecommendations and/or vote on the chat room name, the system-supporteddescription of the room, the position in the domain hierarchy where thecontrolling node for this chat room will be disposed (nodecategorization), the cross linked related rooms to which this room willpoint, the cross linked related nodes to which the node of this roomwill point, and other such mutually agreed to and shared informationconcerning characteristics of the given room. In one embodiment, eachCRS also receives and processes explicit or implicit votes regardingcontent within the rooms under its control, such as votes cast in theform of Cvi's. The CRS may control cleaving of the room into pluralrooms so as to separate warring factions and/or such as to merge lightlypopulated and co-compatible rooms so as to attain a predefined criticalmass of participants in one room for purpose of keeping the discussionsgoing. Each CRS (e.g., 418) may maintain interoperative interfaces withthe other services (e.g., 411-416) in its own data center or even inother data centers for the purpose of support client operations andcarrying out workload balancing.

In one embodiment, chat content messages and other chat-related featuremessages are passed through the CRS hosting the chat room when movingbetween the chat room and the clients in that chat room. The CRS canthen control discourse between users, by for example, banning offensivelanguage or reporting suspicious activities to proper authorities. TheCRS can also thereby detect changes in the primary topics beingdiscussed within the room. As chat room conditions change, the CRS sendsnotifications to the DsMS that currently owns the chat room. Thesenotifications may include information about: (a) Users entering orleaving the chat room; (b) Names or descriptions assigned to the chatroom by its current participants; (c) Changes in the average (or median,etc.) CpCCp and/or DsCCp attributes of the chat room (which may indicatethat the character of the room is changing because a new user populationis moving in and an earlier is departing); and other such chat roomspecific information. If the character of a given room changessufficiently, the supervising DsMS may responsively send a request tothe supervising AARMS requesting a recategorizing of the room such thatit is perhaps moved automatically or by user-approving vote to adifferent node in the domains hierarchy and/or pointers for interrelatedrooms or nodes are changed to reflect the newly acquired character ofthe given room.

Incidentally, in one embodiment, users are allowed to present themselvesin various chat rooms (per their choosing and if allowed by predefinedroom policies) under fictitious user names and/or as anonymous and yettheir acquired ratings of topic proficiency, user credibility, etc., maybe retained. The fictitious user name and/or anonymous feature may bevital for the safety and/or privacy concerns of certain users. Forexample, one user may be a diamond wholesaler who just received a newshipment of high quality diamonds. He of course does not want toadvertise to the whole world his real name or the location of his store.Nonetheless he may want to publicize the event to a trusted usercommunity, where later; trusted members of the community privatelycontact him for more information about his actual name and storelocation. Accordingly, in a system where fictitious user names arepermitted and yet the system needs to keep trending data on the varioususers, a secured lookup table is maintained so that system servicemodules (but nobody else, except perhaps authorized systemadministrators) can lookup the user's real identity and attributecorresponding trending data to his or her account.

Referring back to FIG. 3C, now that many of the larger picture aspectsof the system have been described, it is worthwhile to revisit detailsof the illustrated embodiment 301. Each topic node (e.g., 450′) operatessort of as a nectar source for attracting to it, busy bee users who areswarming about (in a virtual sense) and trying to locate and touchcertain system nodes (again in a virtual sense) in the hopes of findingmatch-worthy chat rooms (e.g., 459 a) attached to the touched nodesand/or in hopes of finding match-worthy other informational resources(e.g., pointed to by 459X′) that are probably on-topic with regard tothe topics the respective busy bee users current have on their minds.When the interested busy bee users (or more accurately their lookupmechanisms) touch on a given topic node (where reference to bees is arough analogy here), they bring with them to the node, certainpollen-like data in the form of the recent CFi data uploads (361, 371)they supplied to their respective DLUX's (362, 372) so as to cause therespective DLUX's to point (363, 373) to the given topic node (450′).This brought along pollen-like data can then be used forcross-fertilization purposes. More specifically, the recent CFi datauploads (361 a) of a given first user are fed into one input of adifference engine 365 assigned to that first user (Sally 121″) while thecollected, recent CFi data uploads (371 a) of other users (e.g., 111″,131″, 141″) who have also recently touched upon that same topic node450′ are fed into a second input of the difference engine 365. (Thetermed, touched, as used in this paragraph is understood to mean thatthe DLUX's 372 of the respective other users scored the “touched” node450′ relatively highly (above a predefined threshold) irrespective ofwhether invitations were sent to those other users and irrespective ofwhether those other users, e.g., 111″, 131″, 141″, accepted theinvitations.) The difference engine 365 automatically filters out theCFi data that is the same as what the first user (Sally 121″) recentlybrought to the node and forwards the not-same remainder data to rankingengine 367. In one embodiment, the ranking engine 367 first parses theremainder data according to type (e.g., URL versus HTML heading versusmeta-tag, etc.) and/or according to the credentials and/or reputation ofthe user who brought that data (which credential, reputation parameterscan be found in the CpCCp file of the respective user). The rankingengine 367 then ranks or weights the remainder data according to one ormore appropriate ranking algorithms. For example, a first rankingalgorithm may call for ranking recently received URL's (found in the CFidata of the remainder data) according to popularity, with the most oftenused URL's being awarded the highest scores. A second ranking algorithmmay call for ranking recently received URL's according to a functionwhich combines (e.g., multiplies) user credential ratings in the topicof the given node (450′) with each instance where the URL is included inthat user's CFi data so as to generate rankings that are weighted byuser credential ratings, with the picks by the most well credentialedusers getting the greatest weight. A third ranking algorithm may callfor ranking recently received URL's according to a trending functionwhich gives greater weight to URL's that have seen a recent upsurge inuse with regard to the topic of the given topic node 450′. Similaralgorithms can of course be applied to other types of CFi data such asrecently used search keywords (216 d in FIG. 2A, 330 b in FIG. 3A),recently used meta-tags (216 f in FIG. 2A, 317 a in 3A), recently useddominant words or phrases (320 c in FIG. 3A) and so on.

In one embodiment, one or more of the ranking algorithms perform theirrespective ranking computations only after a newest group of N users (Nbeing a relatively large number such as 100 or more if the node isheavily used) have touched the node with relevant new CFi data. Beforethe Nth new user touch is detected, the collected CFi data of othertouching users are simply stored for future use. The ranking is thendone by first filtering the collected data to identify relevant datatrends (e.g., major new shift of per-room or per-node common URL's orother topic clustering data) based upon what was stored in the trendingdata store. The value of N can be varied based on the workload of thesystem and/or the historical usage load of the given domain or node sothat N=1 if the system is under a light load (or the node is not heavilyused) and N=(some large number) if the system is under a very heavy loadand/or the domain or topic node is a heavily used one. Storing theranked results only every Nth time can allow for offering of newrecommendations to other users to be done faster because fewer real-timecalculations will be needed by the ranking engines. In one embodiment,an appropriate sorting algorithm for sorting among the ranked items ischosen for each user based on the user's profiles. After suchuser-appropriate ranking and sorting, the list of ranked an sortedresults is culled by subtracting out any duplicate results that matchdata supplied by this user so they are not given recommendations of websites they have just come from. Such an every-Nth-touching techniquecould automatically provided for culling away of aged or stale olderrecommendations so that users receive fresh and often newerrecommendations each time they accept a further research recommendation,where the recommendation(s) are supplied by the ranking algorithms.

The ranked output(s) of the ranking engine 367 are then fed to a sortingengine 368 which uses a user appropriate sorting algorithm (appropriatefor first user 121″) for picking out the best of the ranked remainderdata to feedback as recommendations (e.g., 355 of FIG. 3B) to the firstuser. One appropriate sorting algorithm may be to simply pick thehighest scored of the commonly popular URL's. another might be to pickthe highest scored of the credentialed URL's. In one embodiment, a datareformatting module 369 reformats the data produced by sorting engine368 into a format appropriate for the first user (e.g., into a matrixformat such as 355 of FIG. 3B) and then downloads (369 a) the formattedresults to the client machine of the first user (121″).

The above described generation of ranked recommendations for the firstuser (121″) is repeated for others of the users (e.g., 111″, 131″, 141″,etc.) whose benign spyware resulted in a touching onto node 450′. It isunderstood that respective instances of engines 365, 367 and 368 areoperatively provided for the respective other users. As a result, anaccumulation of best ranked recommendations are generated for thecommunity of users who are recently touching upon node 450′. Module 375automatically collects the best ranked (e.g., highest scored and mostoften repeated) recommendations produced for the users clustering aroundnode 450′, deletes duplicates among these (after scoring them forpopularity) and saves them into accumulated recommendation files (notshown) pointed to by pointers 459X′ of node 450′. Module 375 also keepstrack of aging and popularity or recommendations and periodically cullsthe accumulated recommendation files (not shown) to remove highly agedand not so popular recommendations. As a result, the accumulatedrecommendation files contain the freshest and most recently highlyranked recommendations for the topic of the given topic node 450′. It isto be recalled that the topic of the given topic node 450′ candynamically change over time, the chat rooms (e.g., 459N) attached tonode 450′ can dynamically change over time, the users actively occupyingthose rooms can dynamically change over time, and so on. Thus it isvaluable to keep the retained recommendations as fresh as possible sothat users can find new recommendations they had not seen before whentheir associated match-making processes re-touch on node 450′. In oneembodiment, highly rated ones of aged and to-be-culled recommendationsare stored in a permanent collection of old but good recommendations andnode 450′ provides a logical link (not shown) to those oldies butgoodies. Eligible premium or other users of the system are empowered toreference the permanent collection of oldies but goodies and pull outold recommendations that might be of interest to them.

Another module 380 in embodiment 301 also receives and collects therecent CFi data uploads (371 a, 361 a) of all users (e.g., 121″, 111″,131″, 141″, etc.) who have recently touched upon topic node 450′. Sameuploaded CFi data such as same URL's are counted so as to determinepopularity of each hinting item relative to the touched node 450′. Someof the accumulated hint data (371 a, 361 a) is given additional weightbased on topic credentials of the user who brought the data to node450′. After counting and weighting, duplicate hint items are deleted andthe remainder are stored into appropriate hint storing slots 454′, 455a′, 455 b′, etc. (456′) of the node. Among the data items stored in thehint storing slots 454′, etc., overly aged and low weighted items aredecayed away over time by action of the hint slots stocking module 380.Accordingly, the hint storing slots 454′, etc., remain filled with thefreshest and most up to date hints used by the majority of users (or bythe most topic credentialed users) in getting to the node 450′ by actionof their respective DLUX instances (363, 372). When a new user has hisCFi data uploaded for purpose of finding a matching topic node, the newuser's DLUX instance can compare the new user's CFi data against thehint storing slots 454′, etc. of node 450′ and other alike structurednodes so as to produce matching scores and thereby determine which topicnodes have topics that are most likely to currently be on the new user'smind.

There is more. Since every user whose node seeking software (or otherautomated node-seeking process) comes to touch on node 450′ (and/ortouches on another such node) brings his or her current personhoodprofile (CpCCp) with him or her, and since that personhood profilecontains demographic information about and/or credentials information of(e.g., column 154 of FIG. 1B) the visiting user, additional modules(e.g., 390) of the system can automatically collect demographic andcredential statistics about the kinds of users who most often visit whattopic node and when and/or under what other surrounding conditions.Marketing and advertising professionals can use the collected statisticsto detect trends in the interests of lay and professional userpopulations in different topics at different times and/or underdifferent other conditions (e.g., holidays, unusual weather conditions,unusual news event conditions etc.) and use the same for real timeadaptive tailoring of their marketing and advertising activities. Alsosince users whose automated node-seekers (e.g., software) touch on node450′ and/or other nodes also bring along the knowledge-base rules setsof the respective users (in the user profiles), further modules (notshown) of the system can automatically collect statistics about thekinds of knowledge-base rules that seem to work best in getting users tothe topics they currently have in mind (this being based on also findingcorrelations between user acceptance of invitations and/or ofrecommendations and the rules that brought them to the given node).These are just a few examples of the kinds of useful statisticalanalysis techniques that may be used to take advantage of the fact thateach individual user self-servingly wants to have his or her node-seekertouch on the topic nodes whose topics are of current interest to thatuser so that the user can potentially receive an invitation to anon-topic chat room or receive an on-topic recommendation or an in-personmeeting proposal. The self-serving activities of many users bring usefulcross-fertilization data to the node in a manner roughly similar to howbees bring pollen to nectar supplying flowers. The disclosed systemgathers on-topic information by having users come to its nodes ratherthan the system having to crawl out over a vast internet looking foron-topic information.

In one embodiment, each heavily used topic node (e.g., 450′, or evenselected not-heavily used nodes) has one or more adaptivelyreprogrammable statistics gathering modules (e.g., 390) associated withit and operatively coupled to the node for collecting statisticalinformation (e.g., demographic information) about the users and/or abouttheir brought-along data (e.g., 371 a, 505 d″, 506 d″) where theautomated node seekers of those users brought them to that topic node(figuratively speaking) like bees drawn to the honey. Each statisticsgathering module (e.g., 390) operatively couples (e.g., viabidirectional link 391) to one or more analysis controlling and analysisprocessing servers (e.g., 395). A controlling one of the servers (e.g.,395) sends data gathering instruction signals to the statisticsgathering module (e.g., 390) telling it what data to gather andoptionally how to initially process that gathered data (e.g., byweighting gathered data with coefficients and/or by averaging data overspecified running windows, etc.) Each analysis controlling and/oranalysis processing server (e.g., 395) can receive gathered data fromplural nodes and/or can control the data gathering activities at each ofthe plural nodes. Bidirectional link 392 represents the data gatheringand gather instructing linkage to the statistics gathering module (like390) of another node. By collecting appropriate statistical data fromselected topic nodes and processing the collected data as may be deemedappropriate for the analysis being conducted, the one or more analysiscontrolling and/or analysis processing server (e.g., 395) canautomatically produce demographic and/or other trending reportsindicating how system users are behaving in fairly recent times(especially with regard to joining real time chat rooms covering certaincurrent event topics). The analysis controlling and/or analysisprocessing server (e.g., 395) can then automatically forward the reportsto requesting ones of marketing and/or advertising organizations andthereby enable those organizations to adaptively adjust their behaviorsin response to what is happening over a relatively current time periodat one or more nodes of the hierarchy tree (e.g., 401 of FIG. 4B).

While actions of modules 380 and 390 have been described with respect tonode-wide CFi data flows and node-wide analyses of the profiles of userswhose topic lookup mechanisms substantially touch upon the node, forexample when hunting for on-topic chat rooms to preferentially inviteeach of the users to, it is also within the contemplation of thedisclosure to perform a parallel analysis of the same kind on apern-chat-room basis as opposed to on a node-wide basis. In other words,the pern-chat-room parallel versions (not separately shown) of module380 automatically each determine the most often included URL's in therecent CFi data flows of users of each respective chat room runningunder the node (e.g. 450′) and store these in the parallelpern-chat-room versions (not separately shown) of storage area 454′.Similarly, the pern-chat-room parallel versions (not separately shown)of module 380 also automatically each determine the most often includedkeyword hints in the recent CFi data flows of users of each respectivechat room running under the node (e.g. 450′) and store these in theparallel pern-chat-room versions (not separately shown) of storage area455 a′. The same applies for the parallel pern-chat-room versions ofstorage area 455 b′ and of the other such areas 456′. Moreover, parallelpern-chat-room versions (not separately shown) of module 390 collectpern-chat-room demographic and/or statistics regarding the users whosetopic lookup mechanisms substantially touch upon the node and thereafterinvite them into (or consider in a significant way to invite theminto—but don't due to higher scoring rooms—) the respective chat roomsrunning under the node (e.g. 450′).

With such information and statistics being collected on a pern-chat-roombasis, it becomes possible to automatically map the respective chatrooms running under the given node (e.g. 450′) relative to the node'smean and/or median of its chat rooms. Some rooms will havepern-chat-room attributes (e.g., most often included URL's, most oftenincluded keywords, etc.) that correlate fairly closely to the node-widemean or median of same attributes of the given node (e.g. 450′). Otherrooms will have pern-chat-room attributes that correlate more poorlyrelative to the node-wide mean or median of same attributes of the givennode. In one embodiment, attribute correlation scores are automaticallygenerated by analysis servers (similar to 395) and the chat rooms thatare most deviant, correlation-wise or otherwise, relative to the node'scorresponding mean or median attributes are automatically identified ascandidates for automated migration to alternate nodes, where therespective alternate nodes have corresponding mean or median attributesthat are more in line with the respective migration candidates'attributes. In one embodiment, the determination to automaticallymigrate a chat room to a new node is also made on the basis of howclustered the users of the room are in topic space to one another and/orhow active the users are or how well populated the room is and what theturnover rate is between users departing the room and new users enteringthe room. A prioritization arbiter decides which rooms to migrate firston this basis. Accordingly, if resource availability is tight, the moretightly clustered and highly populated ones of deviant rooms will bemigrated first and perhaps less focused and less active rooms, even ifthey are more deviant may be migrated later or not at all. As mentionedelsewhere herein, room users may alternatively vote on migrating oftheir room to a new location in the hierarchy tree and/or in topicspace. In one embodiment, the more deviant of rooms are migratedautomatically without use of user votes while less deviant rooms thatare currently populated with a predefined quorum of vote eligible usersmay require the migration to be approved by the vote eligible usersbefore being migrated.

Referring now to the Global Services Directory Data Store (GSDS) 431associated with each data center (410, 420, etc.) shown in FIG. 4A, thisGSDS functions as a central repository, whose data is available to allAARMS's in the network, and it stores information about all availableservices at least in its own local data center (e.g., 410) and in apredefined set of sister data centers to which the local AARMS canoffload work to. The local and remote Activity Monitor Services (AARMS)can use this data when making decisions regarding work loaddistribution. In one embodiment, the GSDS stored data includes adatabase table having the following columns:

-   -   Column_(—)1: Service Type—(Rows are: User Account service,        Activity Monitoring service, Domain Lookup service, Matching        service, Chat Room Management service, and there could be more        or specialized variations of these services);    -   Column_(—)2: Current Network Access path—(URL or IP Address used        to access the respective service type from the client        machines—this information is downloaded to and stored by the        respective client machines, 440 a, 440 b, etc. when they        establish contact with a given data center);    -   Column_(—)3: Default Home Region—(Defines the geographic area(s)        best served by the respective service, based on population        demographics and the physical locations of the servers that can        provide the respective services);    -   Column_(—)4: Minimum workload threshold—(If a respective        service's current workload (e.g., clients served per second) is        less than this predetermined number, it becomes a candidate for        being shut down to save power and to have its current workload        consolidated into another server of the same type that currently        has workload slack sufficient to absorb the to-be-consolidated        workload);    -   Column_(—)5: Maximum workload threshold—(If a respective        service's current workload is greater than this predefined        number, then the respective service becomes a candidate for        having its work split and having one or more of the split apart        portions distributed to other services (e.g., remote services)        of the same type); and    -   Column_(—)6: (AMS Assignment—the Activity Monitor Service        (AARMS) that is the current owner (supervising Parent) of this        service).

As indicated above, for other than the AARMS service; each in-datacenter service (e.g., 412-418, but there could be more) will have asupervising Parent AARMS watching over its workload. The supervisingParent AARMS need not be a local AARMS. Additionally, although therespective supervising Parent AARMS are/is primarily responsible forassigning jobs to the respective in-data center services, other AARMS(e.g., remote ones) can also assign jobs to the respective in-datacenter services after getting approval from the respective supervisingParent AARMS. During start up of a data center, the local AARMS (Accessand Accessible-Resources Monitoring Services, e.g. 411) will each fetchfrom its local GSDS (e.g., 431) a list of the services under itsassignment (for which the AARMS acts as the supervising Parent) andcurrent settings of those assigned services. GSDS assignment data iscontinuously mirrored from one data center (e.g., 410) to the next(e.g., 420) so that data centers at least of a given geographic regionif not globally across the network are aware of which AARMS is theprimary supervisor for which on-line service. GSDS assignment data (in431) is updated when: (a) one or more new services are added to thecorresponding data center; (b) characteristics of an existing servicesare changed (an example of this may be when workload threshold settingsare upgraded because getting the physical or virtual server hosting therespective service is upgraded); (c) one or more on-line services go offline (for maintenance or other reasons) and (d) primary responsibilitiesfor one or more services are transferred from one AARMS to another.

As already indicated via FIG. 4B, the Domain Configuration Data Store(DCDS, 435) in each data center stores data representing a hierarchy ofdomains and topics and associated attributes of each domain, topic,subtopic, etc. The associated attributes may include: (a) the domain ortopic node's primary name; (b) the specific location in the domainhierarchy to which the node is assigned; (c) a set of CFi hint or cluevalues that may be used during topic lookups for correlating the givendomain/topic node with probable interest by the CFi's user; (d) a listof current chat rooms in use or available for use by users correlatedwith the domain or topic of the corresponding domain or topic node; and(e) counts of the number of users per chat room using the room and themaximum and/or minimum number of users allowed for the respective roomand/or activity rate of the chat room (e.g., transactions per hour orper day—where this might be a criteria for a user to want to join or notthe room based on the speed of activity by other users). The hierarchyrepresenting data in the DCDS 435 of a given data center may be mirroredto multiple physical storage locations within the same data center andalso into backup storage units in other data centers. Mirroring of suchdata can help distribute the read load of the main DCDS 435 in the datacenter and thus improve the speed with which client machines can readthat data from over the network 430.

Referring to the Trending Data Store (TDS) 437 of FIG. 4A, this storageis used for maintaining histories of user activities and detectingtrends of behavior (and/or instance of abnormal behavior) by individualusers (across the entire system) as well as by user populations on a perdata center basis and/or on a per domain and/or topic basis. Storedtrend data is accessed by one or more system trend data analysisservices (not shown, can be shared by plural data centers) which usesthe data to make system alteration determinations such as: (a)determining when new domain and/or topic nodes should be created orobsolete ones should be deleted from the DCDS (435) of a given datacenter based on user population activity at that data center; (b)determining when the common CFi hint parameters (e.g., 454, 455, 456)associated with a respective domain and/or topic node should be modifiedto conform to changed behavior by user populations; (c) determining whenand what adjustments should be made to CpCCp's and/or DsCCp's ofspecific users based on historical analysis of their Cvi's so that theCpCCp's and/or DsCCp's reflect the actual preferences of these usersbased on how they actually behave rather than just on how they respondto surveys about their stated preferences; (d) determining which populardomain and/or topic nodes should be featured as user-recommended domainsor topics on one or more system provided, Most Popular Topics web pages(not shown) thereby providing users in given geographic locations and/orusers having certain general preferences with real time changingadvisements as to what chat room topics are currently most popular forlike situated other users, where these “live” popularity sites providesliving examples of such on-topic chat rooms and provide hyperlinks tosuch popular chat topics thus giving visiting users the ability toeasily join corresponding on-topic chats by single clicking on thehyperlinks. The system trend data analysis services can further use thetrending data to (e) determine when and how a specific user's preferenceprofiles should be adjusted based upon trends in their browsing and/orchatting history. For example, the system may determine from trendingdata that the given user prefers chatting with argumentative people whendiscussing soccer even though the user specified in his CpCCp or DsCCpthat he prefers to chat with agreeable people regarding the topic ofwhich regional team is the best soccer team. In one embodiment, thesystem trend data analysis service does this by automatically comparingthe overall temperament of other users in each soccer related chat roomthe given user has recently visited and chatted on to the actual degreeof involvement by the given user in those contentious rooms and/or tothe lengths of time spent by the given user in those apparentlycontentious rooms. In other words, even though the given user states inhis self-filled preference survey that he likes noncontentious rooms forthis given topic, his actual behavior indicates that he prefers theexact opposite. In one embodiment, the user's preference for contentiousversus noncontentious rooms or vise versa are detected by automaticallylogging the user's biometric data (e.g., increased heart rate, breathingrate etc.) at his local computer, uploading these to the associatedTrending Data Store (e.g., TDS 437) and then causing the system trenddata analysis service (not shown) to infer the same as being temperamentmeasurements and then to correlate these temperament-representingmeasurements to the different topic nodes through which the user entersinto the various chat rooms. The system trend data analysis serviceperiodically reviews stated preferences versus temperament-indicatedpreferences and adjusts CpCCp's and/or DsCCp's to reflect actualpreferences as opposed to self-described preferences. It is to be notedthat although descriptions herein of the other in-data center servicesdo not mention the Trending Data Store (e.g., TDS 437), in oneembodiment, each of those other services routinely submits behavioraltrend related data to the user-associated TDS in order to log theactivities for later analysis.

Referring to the disposition of the plural data centers (e.g., 410, 420,etc.) of FIG. 4A, it is to be noted that the hosting of the various chatsupporting services (e.g., 411-418) on plural servers that aredistributed among physically separate datacenters provides benefits suchas: (a) the match-making services can remain available to clientmachines in different geographical locations even if a local homedatacenter goes off line. The client machines are programmed to try andconnect to the AARMS and/or UAS of alternate data centers (e.g.,secondary home) if connection to the primary home center fails for apredetermined number of consecutive retries. Outages at specific datacenters may cause certain pre-existing chat rooms to be temporarilyunavailable. However, system users will still continue to be invited tojoin alternate chat rooms (for the same topic and having similarco-compatibility attributes) hosted by alternate data centers, and thusoutage at one data center would not result in a complete service outage.By using plural regionalized data centers (e.g., one for every so manysquare miles or for a predetermined number of users) another benefit is(b) that each data center can have its resources custom tailored toprovide optimal performance for its particular geographic region. Forexample, an island (i.e. Taiwan) may have a high speed internetinfrastructure within the island, but a slower connection to the rest ofthe world. Placing a data center with high speed connectivity directlyon this island would provide optimized performance for its residents.The number of datacenters within a geographic region, and theconfiguration of the servers within the data centers, can vary based onhistorically observed load requirements and trends. The combination ofservices running on servers (virtual or real) distributed in acooperative group of datacenters may be referred to as an in-cloudcooperative group.

An in-cloud cooperative group may grow and evolve as the number of usersand/or their geographic displacements increase. During periods whenusage is expected to be light (e.g., during initial alpha testing or ina region where adoption rates are low), a single physical server withina single data center may suffice to host all of the services for thatbudding data center. However, as more users in a region discover theadvantages of automated invitations to chat rooms that have beenpre-screened for topic and personal co-compatibility, the concomitantincreased usage expectations will warrant placing multiple physicalservers within the single and still nascent datacenter. Each of thesephysical servers may host one or more of the in-data center services.However as usage increases yet further and a single data center can nolonger provide sufficient the robustness and reliability of service to apopulation users with growing demands, it will become desirable to sharework loads among services running in multiple datacenters where the datacenters (e.g., 410, 420, etc.) are configured to communicate with eachother via a private network 439. More specifically, as mentioned above,it may become advantages to merge services dedicated to esoteric topicsand small user populations into relatively slower and smaller serverswhile splitting services dedicated to highly popular topics and havingvery large and growing user populations among a plurality of higherspeed and larger servers. Thus cost of services is allocated based onthe desires of the user population.

Referring again to the AARMS units (411, 411′) in each of the datacenters of FIG. 4A, there can be multiple ones in each data center. Theycan operate as virtual instances and/or as physical units. Only oneAARMS instance per center was initially assumed in order to simplify theintroductory discussion. Each AARMS (Access and Accessible-ResourcesMonitoring Service) maintains a pool of its own servers (acts as thesupervising parent of those servers) where the AARMS owned serversprovide corresponding non-AARMS services such as 412-418. Each AARMSalso acts as primary home access point for an assigned set of clientmachines. (The client machines initially try to connect to that AARMSwhen logging-in into the system.) The number and speed of resources ineach AARMS controlled pool is adjusted by system administrators on aperiodic basis to ensure that no server or service has too much of aworkload (due to too many client machines and/or too many power users inthe corresponding user population) and that no match-making cluster hasso few clients that it cannot offer a sufficient number of co-compatiblechat opportunities to its client respective user population.

When an AARMS instance (e.g., 411) starts up, it accesses itspre-assigned service directory (e.g., 431) to get a list of theresources it is primarily responsible for and also a list of resourcesat its disposal for off-loading excess work to. While running, the AARMSwill keep track of how each of the service resources it owns is beingutilized (e.g., what slack in bandwidth is available). Each time aclient machine (e.g., 440 b) initially tries to connect to its home datacenter via public network 430, the client machine first tries to connectwith its pre-assigned home AARMS. If this fails, the client machinetries an alternate AARMS and works down a list provided for example on adedicated web page or as on-network list (dedicated for providing a listof alternate AARMS). The AARMS which picks up connection with asigning-in client machine first interacts with a corresponding UAS 412(that holds a copy of that user's records) to assure that the userpassword and/or other security measures are properly met for validsign-in. Once valid sign-in is established, the primary contact AARMSpulls the user's primary CpCCp from the UADS 432 (one that holds a copyof that user's records) and examines the pulled CpCCp in order todetermine which other datacenter and other AARMS (with associated DLUX415) if not the current AARMS, is best suited for servicing the user'sgeneral preferences (e.g., favorite topics as listed in area 154-7 a ofFIG. 1B for example) given the user assumed current mood. Choice of bestsuited other AARMS may be based upon the current work loads of theprimary contact AARMS, on the openings or slack bandwidth available inchat rooms in the current data center which the signing user is likelyto want to enter given the user's CpCCp preferences, on the alternatedatacenter's geographic location and/or speed of access, or other suchfactors. Depending on how workloads of service resources within thecontacted datacenter change, the client may be sent by the current AARMSto another AARMS either in the same data center or in another datacenter. For example, if a given AARMS reaches either its minimum ormaximum workload thresholds, it will look for other AARMS instances totransfer some or all if its clients to. In one embodiment, an AARMS'sworkload (e.g., 411′) is determined primarily by the sum of theworkloads of all the DLUX (e.g., 412′), DsMS (e.g., 415′), and CRSservices (e.g., 418′) assigned to that AARMS. In the same or analternate embodiment, reaching of the AARMS's maximum workload thresholdmay be defined by the reaching of a respective maximum workloadthreshold of anyone of the DLUX, DsMS and CRS services assigned to thatAARMS or by the reaching of a summed maximum workload threshold of aprespecified subset of the services the given AARMS directly supervises.

An overloaded AARMS may automatically request, or an under-loaded AARMSmay automatically respond to a request from another AARMS (either in thesame data center or in a remote data center), to transfer serviceassignments between AARMS's. This control process will allow the AARMS'sto automatically reallocate services as workloads dynamically changethroughout the day. An example of this may be where there is one AARMSper geographic region with each AARMS having a set of default serviceshosted for that area. There may also be a set of non-default servicesthat are not assigned to each geographic region but are insteadmaintained only in certain data centers due to lack of popularity.Supervision over any one or more of the default services or nondefaultservices may get transferred between different AARMS instances as theworkloads of each AARMS in each geographic region changes. Servicesassigned to one geographic region during that region's peak hours of forexample the afternoon and evening may not be needed during the slowhours of that region, for example in the early morning. Accordingly,underloaded service providers (e.g., AARMS, UAS, DLUX, DsMS, CRS units)in a currently slow region can be lent out by the data center of thatslow region to relieve the burdens on a heavily loaded data centeroperating in a different time zone. Thus, the distributed data centermodel with individually distributable service providing resources candynamically shift workloads to accommodate dynamically changing demandsof the regional user population.

One of the primary tasks of an AARMS, when servicing a given clientmachine (e.g., 440 a) is to receive and parse data from CFi's (e.g., 118a) and from Cvi's (e.g., 118 b) transmitted form the client machine(e.g., 115 of FIG. 1A), to regroup the parsed data if needed, and tooffload the tasks implied by the respective data groups obtained fromthe CFi's and Cvi's to respective DLUX services (for topic look up) andCRS services (for chat room management and recording of trend data intothe TDS 437). Accordingly, an AARMS will do the majority of its work inresponse to receipt of CFi's and Cvi's from respective client machines.This will begin to occur after the client machine has signed-in (loggedin) into the system or after the client machine has been redirected tothe current AARMS instance from a different instance of an AARMS.Although log-in and redirection may be a frequent occurrence, it willgenerally be much less of a frequent occurrence than the primary task ofthe AARMS, namely, the processing of received CFi's and Cvi's. In analternate embodiment, Cvi upload data may bypass the AARMS and godirectly to the CRS so that the CRS collects votes for voted-upon items.Also, in a same or alternate embodiment, parsing and grouping of CFidata items may be handled by the DLUX services rather than by the AARMS.In such a case, the AARMS merely manages balancing of workflow and theassigned DLUX instance takes on the burden of actually processing theCFi data stream inflow from a respective user or plural users.

The following is an exemplary walk showing a case where a client machinefails to connect to its default primary home AARMS. (Identity of theprimary home AARMS and secondary home AARMS and of a web page or otheron-network list where further alternated contact AARMS's can be foundare stored in one embodiment, in the client machine as part ofinstallation of software package 105.) When the exemplary client machinefails to operatively link with the first AARMS, the next AARMS itcontacts then redirects the client to a third AARMS which finallyaccepts the request and begins to route CFi's received from that clientmachine to an assigned DLUX service under the third AARMS's supervision:

Step 1. As client software (105) starts in a client machine, it providesuser authentication credentials to the primary home AARMS with theexpectation that the primary home AARMS (say 411) will pull the user'srecords from the home UADS 432 and interact with the local UAS 412 tovalidate the sign-in, after which the primary home AARMS 411 shouldassign one of its DLUX services (only one, 415, shown in FIG. 4A) toprocessing CFi's routed from the first AARMS to that assigned DLUX.However, the first AARMS may determine that it itself is overwhelmed (atmaximum summed threshold) or that it has no DLUX with slack bandwidth toassign this new coming client machine to. So the first AARMS signalsback that it is not available or the first AARMS does not respond andthe client machine runs a timeout counter that indicates to the clientthat the first AARMS probably will not respond.

Option 1a. The first AARMS may not respond because it is in an “offline”status.Option 1b. Upon the client machine receiving the not-available signal orthe timeout counter of the client running out, the client tries toconnect to a next AARMS resource in its stored list or web accessed listof known AARMS resources.

Step 2. The second contacted AARMS responds affirmatively to the clientmachine that contact has been made and the second AARMS (e.g., 411′)accesses the user's account data either from a locally accessible datastore (UADS 432′ in center 420), or if the user's records are not there,via the backbone and private network links 417′-439-417 from remotestore 432 in another data center (e.g., 410). The fetched user's accountdata is used to:

Substep 2a. Validate the client's login credentials.Substep 2b. Obtain the client's current CpCCp (e.g., 105 h.1 of FIG. 1B)and optional DsCCp's (e.g., 106 h.1 of FIG. 1C).

Step 3. The second AARMS then accesses its service directory data store(431′) to determine if, given the client's preferences as indicated inthe fetched CpCCp and DsCCp's, whether the client should be redirectedto a different AARMS instance that is better suited to handle thisparticular client. If so, the second AARMS transmits a signal to theclient indicating that the client is being redirected and providing theURL or IP address or other link to the third AARMS which the client isnow being bounced to. One reason why a different, third AARMS might bemore appropriate is because this user's CpCCp and/or DsCCp's indicatethe user has highly esoteric needs for which chat rooms that areaccessible to the third AARMS might be needed. Such a bounce over mayhappen if for example:

Option 3a. The third AARMS is geographically closer to the clientmachine and/or the third AARMS can offer a higher turn-around speed tothe client machine (e.g., a roaming cell phone with computingcapabilities) and the third AARMS has sufficient load capacity to takeon the service needs of the user and/or his currently utilized clientmachine.Option 3b. The second AARMS is near its workload capacity and there areother AARMS instances available with spare capacity and with the abilityto meet the client's bandwidth requirements (e.g., high ones if theclient is a premium service user or lower ones if not subscribed to apremium service).

Step 4. In response, the client machine makes contact with the specifiedthird AARMS (which AARMS will generally accept the contact requestbecause it has been pre-instructed to by the second AARMS, in otherwords, the second AARMS already made a reservation for this clientmachine in one of the available time sharing slots of the third AARMS).The third AARMS (not shown) will now access its local UADS (like 432′)to thereby locally gather the user's account information (and if notthere, will fetch the data from another UADS) and then the third AARMSwill access its local GSDS (like 431′) in order to determine which ofits supervised DLUX's is best to route this client's CFi's to:

Option 4a. If only one DLUX is active, the third AMS will route allclients to this single DLUX.Option 4b. If multiple DLUX's are active and available, the third AARMSwill selectively assign the client to a DLUX in a manner that spreadsthe load among its plural DLUX's as evenly as currently possible.

Step 5. The third AARMS will begin forwarding the CFi's from thesigned-in client machine to the selected DLUX instance. In an alternateembodiment, the third AARMS signals to the client which DLUX resource touse and the client machine then responsively begins to forward its CFi's(e.g., 118 a of FIG. 1A) directly to that DLUX resource therebybypassing the third AARMS. In yet another alternate embodiment, thethird AARMS signals to the selected DLUX resource, the address of thesigned-in client machine and the selected DLUX resource then begins topull CFi's from the client machine via the public network 430 (wherethose CFi's can be encrypted when passing over the public network 430).In yet another alternate embodiment, the third AARMS parses CFi's pulledby the AARMS from that client machine to determine at least a moreprobable domain associated with each CFi or group of CFi's and the AARMSthen routes the parsed and optionally grouped together CFi's todifferent DLUX resources that are each specialized with performing topiclookup under that specific domain. An example of where grouped CFi'smight be differently processed for topic lookup under different domainsmight be where the domains have different cultural biases or idiomaticcontexts and a phrase such as, “there is more than one way to skin acat” may have entirely different meanings in a domain involvingdesigning computer-implemented processes as opposed to surviving in thewilderness. After the DLUX instance determines a probable specific topicfor the client's recent CFi's, it flags the AARMS with informationindicating the topic node and the AARMS then activates a nodespecialized match service (416′) to find or create a co-compatible chatroom for that user and that identified topic node.

Step 6. If during all this processing, the third AARMS discovers that itneeds to rebalance its loads because a threshold is being approached orhas been passed, the third AARMS may elect to redirect selected clientsto yet different AARMS instances, especially if the clients arenon-premium service ones. When this happens, the process restarts atStep 3 except for a differently numbered, Nth AARMS in this case.

As workloads at specific data centers increase due to increasing numbersof signing-in clients, an automated data center managing service (notshown) may responsively decide to fire up more physical servers wherethose servers had been kept idle in order to conserve data center energyutilization. As the new servers power up, they will instantiate newAARMS instances. As each instance of an AARMS starts, in one embodiment,it sequences through the following steps:

AMS Step 1. The starting up AARMS instance gets the list of servicesresources it owns (its supervised child services) from the servicedirectory data store. The assignments in the service directory datastore (GSDS) are initially set when new services are added to the datacenter. Current assignments in the GSDS (431) are updated when servicesget reassigned during load balancing operations.

AMS Step 2. The starting up AARMS instance initializes each of its childservice resources, by sending initialization instructions and gettingstatus reports back, for example in the following order:

AMS SubStep 2a. All online and available CRS Resources (418);AMS SubStep 2b. All DsMS Resources (416). Part of this process mayinclude:AMS SubStep 2b(i). Assigning specific CRS resources for each the DsMS'sto use.AMS SubStep 2b(ii). Optionally, assigning specific domain and/or topicnodes listed in the DCDS (435) that the respective DsMS's should beresponsible for and thus specialize in making co-compatibility matchesfor.AMS SubStep 2b(iii). Optionally, creating default chat room(s) (e.g.,empty or populated with an automated moderator) for the assigned domainand/or topic nodes in accordance with the hierarchy definitions providedin the DCDS (see FIG. 4B). The starting up AARMS instance may do this bysending “create chat room” instructions to each of the respective CRSinstances together with a pointer to the assigned hierarchy node ornodes and by receiving a confirmation status regarding successfulinstantiation of the desired number of initial chat rooms for each ofthe assigned domains and/or topic nodes.

AMS Step 2c. The starting up AARMS instance initializes all of its ownedDLUX Resources (415). Part of this initialization process may includeindicating which DsMS resource the DLUX instance should route itsmatch-making requests to after having performed a lookup and identifieda probable domain and/or topic for a corresponding one or more processedCFi's. In one embodiment, the initialization process also includesindicating which DsMS resource the DLUX instance should route itsmatch-making requests to if the lookup failed and the CFi(s) is/areinstead deemed to be dealing with a default catch-all domain and/orcatch-all topic and where the client is thus to be invited to acorresponding catch-all chat room that contains or is to containpersonality-wise co-compatible other users. Of course, many variationson which unit asserts control and delegates tasks to the other arepossible. In one embodiment each DLUX is made responsible fordetermining the target number of topic node matches it will look for andthe time out of when to stop looking. Thus in such an embodiment, theDLUX, and not the AARMS, is the controlling factor which determines howmany invitations if any at all, each user will receive. In an alternateembodiment, the supervising AARMS may have override abilities, such asstopping a DLUX before it reaches its target goal of number of topicnodes found and instructing the DLUX to begin a new lookup, perhaps fora premium subscription client. After a DLUX finds whatever number ofmatching topic nodes and scores them, either the supervising AARMS, orthe DLUX, may forward the scored results to a DsMS instance and initiatethe DsMS match making process for that topic node (where the DsMS matchmaking process scores possible chat rooms based on co-compatibility andreturns scored links to chat rooms that appear to be most co-compatiblewith the given user).

AMS Step 2d. The starting up AARMS instance initializes all of its ownedUAS resources (432, only one shown). At this point, the starting upAARMS instance can begin to accept client linkage requests and to startservicing those requests. In one embodiment, the availability of the nowstarted up AARMS instance is published into the GSDS (431) of at leastthe local data center and more typically into the GSDS (e.g., 431′) ofsister data centers so that overloaded other AARMS can bounce theirexcess workload to the now started up AARMS instance. In one embodiment,availability of the now started up AARMS instance is also automaticallypublished into the list of alternate AARMS which client machines can tryto connect to when linking to the match-making system.

AMS Step 3. Some aspects of the AARMS initialization process that may becommon to all child services are:

AMS Step 3a. Informing each child service how it can connect with andcontact with the supervising parent AARMS in order to establishasynchronous two way communications via a local backbone (e.g., 417) orover multiple backbones and private networks (e.g., 439). Theasynchronous two way communications may be packet based serial ones inaccordance with industry established protocols for the same or they maybe proprietary ones.AMS Step 3b. Requesting current status from each child service.AMS Step 3c. Updating the local GSDS (431) to indicate currentassignments made by the AARMS for its supervised child services andmirroring the assignment information to other GSDS's (e.g., 431′) inother locations.

The DLUX services take on the job of looking through the user's CpCCpand DsCCp's and trying match these with the help of hints in the CFi'sto the more probable domain and/or topic nodes to which the DLUX servicemay be assigned (it could be to all domains). Since the DLUX serviceshave continuous work of sustainably performing lookups for inflowingCFi's it is desirable to prevent each from becoming overwhelmed.Typically an AARMS will simultaneously start all of the DLUX resourcesit has available so that it can distribute its client jobs to them in amanner that balances the load and assures that all client machines willget relatively rapid response to their CFi submissions. In oneembodiment, if the active client population for a given AARMS is morethan its current pool of DLUX resources can handle, the AARMS will takethe steps listed below.

DLUX overload Step 1. When a parent AARMS detects (through periodicchecking of workload levels such as examining backups of requests inbuffers or getting pressure push back packets) that one of its childDLUX resources is trending towards reaching its maximum workloadthreshold or has reached it, the AARMS will start looking for alternateavailable DLUX resources to reassign some of the workload to:

DLUX overload Step 1a. First the AARMS will begin by checking its ownpool of services to see if there is an unused DLUX resource that can bebrought online but has not yet been activated, if not;DLUX overload Step 1b. The AARMS will start making requests for transferof unused or lightly loaded DLUX resources from other AARMS instances inthe same or in remote data centers, where a lightly loaded other DLUXresource will first have to divest itself of current jobs or it willhave to partition itself to create a supervisable subpartitioncontrolled by the requesting AARMS (or by another AARMS) beforeindicating availability to the requesting AARMS.

DLUX overload Step 2. If an available DLUX full resource or subpartitionis found, then:

DLUX overload Step 2a. The requesting AARMS will start to redirect newclients to the new DLUX resource either directly or by redirecting theclients to the alternate AARMS which controls the found and availableDLUX full resource or subpartition.DLUX overload Step 2b. The requesting AARMS may also or alternativelyinstruct the heavily loaded DLUX resources to bounce back some of itscurrent client jobs to the AARMS, at which point the AARMS will forwardthese to less loaded ones of its directly supervised DLUX resources.

DLUX overload Step 3. If an available DLUX resource is not found, theAARMS having the heavily loaded DLUX will determine if there are otherAARMS instances locally or remotely that can take over the excess workand possibly increasing load. If so:

DLUX overload Step 3a. The overloaded AARMS will begin redirecting allnew clients to the alternate AARMS, additionally:DLUX overload Step 3b. The taking over new AARMS may instruct theheavily loaded DLUX to bounce back some part of its still not servicedand current clients over to the alternate AARMS. this can help to clearthe backlog in the input buffers (not shown) of the heavily loaded DLUX.

DLUX overload Step 4. If the overloaded AARMS cannot rebalance its DLUXwork loads by the above methods, the local DLUX resources and/or theoverloaded AARMS will start to implement load throttling techniqueswherein they simply drop some of the client sourced job requests(arising out of uploaded CFi's). In one embodiment, load throttlinginstructions or backpressure flags are downloaded to the clients as partof their next Cciv posts. The client machine may optionally flag anindication to its user apologizing that the chat room invitationsservice is currently in a throttled down mode. In the same or anotherembodiment, load reduction may be implemented by the cloud downloadingnew CFi filtering requirements to one or more of the client machines soas to thereby reduce the amount of uploaded CFi data. For example, a newCFi filtering requirement might indicate to the instructed clientmachine to temporarily increase your threshold for sufficient biometricintensity for recording the biometric event in the CFi buffer by 10%. Inresponse, where the minimal increase of user heart rate was 5% towarrant recording, now for a predefined amount of time it will be raisedto 5.5%. Thus the amount of uploaded CFi data will tend to decrease. Thenew CFi filtering requirement instructions provide the cloud with amethod of fine tuning the rate at which CFi data is uploaded to it andof placing the filtering workload in the laps of the client machines.

After a DLUX resource finds a probable match between received CFi's anda given domain and/or topic node, it falls to one of the DsMS resourcesto find the appropriate chat room under that looked-up domain and/ortopic node that is co-compatible with the corresponding user. Thematch-making services (DsMS's 416, 416′) can work most efficiently whenthey can provide chat room matches for the pool of clients assigned tothem via the local AARMS without having to do global searches across allpossible chat rooms. In order for the co-compatible aspect to workeffectively, each DsMS should receive jobs from a sufficiently largepopulation of different clients so as to be able to provide good chatopportunities to co-compatible clients. If the population of differentclients is too small, the DsMS may not be able to make a match thatfully or partially satisfies the co-compatibility preferences of two ormore members of the serviced population. On the other hand, if theto-be-serviced client population is too large, the DsMS may not have thebandwidth to make matches in a timely manner. One of the ways to controlthe size and diversity of the client population that is to-be-servicedby a given DsMS (e.g., 416′) is by changing the number of domains and/orthe number or identities of the topics covered by that DsMS.

In one embodiment, in order to provide an optimal load for each of theDsMS resources, specific domains (and/or specific topics under thosespecific domains) are assigned to the respective DsMS resources by thesupervising AARMS and the assigned specific domains/topics are marked asbeing serviceable either only locally or globally. What is meant here by“locally” is that chat room matching services are provided only for thelocal AARMS that owns the local DLUX and the local DsMS and the DLUX wasservicing the CFi's of a user for which this data center is a defaulthome center or a default secondary home (backup home). This assures thathome town users will not be deprived of minimal bandwidth when a surgeof out-of-town CFi servicing requests comes streaming in, due forexample outage at a nearby data center. What is meant here (in thisparagraph) by “globally” is that chat room matching services areprovided for out-of-data center requesters also. DsMS load control mayinclude the following steps:

DsMS load control Step 1. When a parent AARMS sees one of its child DsMSresources reaching its maximum workload threshold, it will look foralternate available DsMS resources to take on some of the workload:

DsMS load control Step 1a. The looking AARMS begins by checking its ownpool of DsMS resources to see if there is an unused (e.g., off line) MSresource that can now be brought on line to the share or split theworkload.DsMS load control Step 1b. The looking AARMS next checks its pool ofDsMS resources to see if there are any underutilized DsMS resources thatcan take on some of the overload by taking on responsibility for some ofthe nodes now handled by the overloaded DsMS.DsMS load control Step 1c. The looking AARMS next issues requests viathe backbone 417 and/or private network 439 for transfer of a MatchingService resource from another AARMS (local or remote) to supervisionunder the looking AARMS.DsMS load control Step 1d. If it gets supervision over a less loadedDsMS, the looking AARMS will begin determining how to reassign one ormore of the domains and/or topics currently being handled by theoverloaded local DsMS resource to one or more of the more lightly loadedother DsMS resources belonging to other AARMS.

DsMS load control Step 2. If an available lightly loaded MatchingService resource has been found

DsMS load control Step 2a. The AARMS looking to relieve one of its ownDsMS's will automatically determine how assignment of the specificdomains and/or topics of the overloaded DsMS should be split up betweenthe fully loaded and the available DsMS other resources. Thisdetermination may be made by:DsMS load control Step 2a(i). Checking to see if a specific globaldomain node has enough client traffic to warrant being split into both aglobal servicing node and a local only servicing node.DsMS load control Step 2a(ii). Determining which one or more of thelightly used domain and/or topic nodes on the heavily loaded DsMSresource can be transferred to the more lightly loaded DsMS resource soas not to overload the latter.DsMS load control Step 2b. If the responsibility for a globally serviceddomain node is transferred to a matching service in an alternate AARMS(in another data center), the originating AARMS will inform all otherAARMS resources of this change via changes to the GSDS 431 and mirroringof the same to other GSDS's (e.g., 431′). Then each AARMS will informall its DLUX resources of this change.

DsMS load control Step 3. If a given AARMS cannot balance its DsMSloads, the local DsMS and/or DLUX resources will start to implement loadthrottling techniques described above for the Matching Service Clientoverload conditions. Portions of the load throttling instructions may besent to clients as part of their next Cciv posts.

In one embodiment, aside from making matches between chat rooms andCFi's of individual users, DsMS instances with spare capacity can usetheir spare bandwidth to make co-compatibility matches between one userand the next (background clustering) even if the users are not currentlyon line. This may be done by crawling through the CpCCp's of users tofind cases of extreme personality-based co-compatibility and/or crawlingthrough the DsCCp's of users to find cases of extreme topic-basedco-compatibility. These results may be stored in the respective user'saccount data store records (e.g., 432). In one embodiment, the systemmay periodically recommend a pen-pal relation or the like to users whohave not previously conversed, this being based on a crawl found extremeco-compatibility involving personality-based co-compatibility and/ortopic-based co-compatibility.

Referring to FIG. 4C, in one embodiment, when a client servicing AARMS(e.g., 411) assigns to a supervised DLUX (e.g., 415) the job of findingthe more likely domains and/or topics associated with a received one ormore of the client's CFi's, the DLUX determines how good of a job itneeds to do. In other words, in one embodiment, the DLUX determines whatnumber N′ of potential domains will be competitively scored and/or howdeep down the hierarchy tree below the domain node level the search willproceed. Assignment of the domain lookup task is through entry path 421a. As indicated in step 421, the extent of the job may depend on thelevel of service the user is subscribed to (e.g., normal, premium,super-premium). The DLUX will set for itself corresponding targetnumbers for the number of chat opportunities to locate for this round ofto-be-processed CFi's and target parameters for closeness of match as totopic and/or user-ton-chat room co-compatibility. High premium serviceclients will of course be given larger target values (unless the usersindicate to the contrary for the time being or system bandwidthavailability is tight for the moment). The larger target values willmean that more chat opportunities (more invitations per unit time) areoffered to the more premium members, better matching forco-compatibility with other chat room partners and better matching oftheir CFi clues to specific topics are offered to the more premiummembers, and so on. Lower service clients will receive poorer resultssuch as a fewer number of corresponding invitations per predefined unitof time and/or poorer matching of topic sameness or userco-compatibility such that the chat rooms they are invited into may notbe exactly on topic, although close enough and such that the chat roombuddies they find populating those rooms may not be exactly inaccordance with the user's CpCCp and/or DsCCp preferences, butnonetheless close enough to be of value to the being-serviced user. Asmentioned above, in one embodiment, users can navigate through thehierarchy searching on their own for a better matching node or roomand/or users can pick the “none of the above” option.

In some instances, a user may have already received more than a targetednumber of good invitations in a recent previous round of lookup andmatching. In this case, depending on resource availability, step 422 maydowngrade the target numbers for this round if local bandwidthavailability is currently tight and the user got a sufficient number ofgood invitations just recently to satisfy the owed quality of service tothat user. On the other hand, if current bandwidth availability isrelatively wide and the user was short changed in the previous round,the target numbers may be upgraded to thereby attempt to satisfy theowed quality of service to the given user. In some instances, the givenDLUX or its whole data center is being overwhelmed with too much workand it needs to throttle down its allocated services for all users. Insuch a case, the target number may be reduced for all users, perhapsless so for premium service users than for lower priority users.

Referring still to steps 421 and 422, in one embodiment, the initial oradjusted chat opportunity target count goal and matching score minimumthresholds are determined based on:

-   -   Presence or absence of redirection instructions from        AARMS-initiated load balancing operations and the severity of        such pending load balancing requests;    -   The number of chat opportunities offered to the same client        fairly recently (e.g., in the past 10 minutes); and    -   The number of chat rooms the client is currently participating        in and the degree of participation. In other words, if the user        of the client machine is busy writing in contributions to a        first chat room, it is unlikely that he or she will have time to        notice new incoming chat invitations and join in those as well.        Thus for a user who is already heavily engaged with a first set        of one or more ongoing chat operations—this status being        reported to the cloud by the user's client machine—the cloud can        respond by temporarily shutting off or substantially throttling        down the number of chat room invitations being currently sent to        that user, in which case the target number may intentionally be        forced down to 0 even though normally it would be a higher        value. As a result of the temporarily forced zero count, step        423 passes control to exit step 423 x and DLUX resources are not        consumed for servicing the user who is already busily engaged        with one or more chat rooms.

In one embodiment, the following general rule is followed:

-   -   The larger the number of recent chat opportunities presented to        the client, the lower the target count will be (in order to keep        the user from being overwhelmed with too many chat opportunity        invitations) and the higher the matching score requirements will        be (in order to ensure high quality matches if invitations are        at all sent, where here, the matching score requirement is a        minimum or threshold score (e.g., co-compatibility score and/or        narrowness of topic score) needed for allowing an invitation to        be sent out)—In one embodiment, the DLUX provides the DsMS with        a target count and a minimum matching score requirement and a        timeout limit so that the DsMS will have guidelines to follow on        how much effort it should spend on trying to make a match. If        the target count has been reached or the sorted scores begin to        fall below the minimum threshold or the timeout limit is        reached, the DsMS can stop;    -   The fewer the number of chat opportunities (Cciv's) offered to a        user relative to an adjusted target count, the lower the minimum        matching score requirements will be made (by readjustment) so as        to thereby find and offer at least some chat opportunities to        the otherwise short changed client. In other words, in response        to failure to find the desired number of high quality matches,        if time has not run out in below described step 426 a, a loop        back to the top of the algorithm will be made where the degree        of closeness of topic co-compatibility and/or personality        co-compatibility will be automatically scaled back so that at        least some invitations are generated even though these        invitations are suboptimal relative to what is indicated to be        desirable in the user's DsCCp's and/or CpCCp.

At step 423 the process determines if the resulting target values, afteradjustment in step 422, are equal to or less than zero. If yes, thereare no invitations to be sent back to the client machine and the jobterminates at exit step 423 x so that the local DLUX resources can beused to service another client. If test 423 results with a No, then instep 423 a the current DLUX fetches the user's PEEP, CpCCp andoptionally her root DsCCp and optionally her topic specific DsCCp's fromthe local UADS (e.g., 432). Step 423 b is the head of domain identifyingloop. If the AARMS and/or the user's client machine have not alreadydone so, the DLUX may use the user's PEEP to parse and group the datafound in one or more CFi's so that parsed and grouped data is likely toindicate probable topic of interest on the user's mind and also thedegree emotional engagement with the topic. Parsed and grouped hint datais sorted so that the hints with the greater degree of emotionalengagement will be processed first by the DLUX. In one embodiment, atleast a majority of the CFi data parsing and/or grouping functions areperformed in the user's local client machine using a downloaded copy ofthe situation appropriate PEEP or a situation selected copy of a locallystored LPeep file (if the client machine has sufficient computationalresources for doing so, that is, the local machine is not for example aminimal function cell phone or the like). This localized parsing andgrouping of the CFi data can improve the chances that the rightbiometric data will be correctly logically linked to its causative andfocused-upon content while at the same time reducing the workload placedon the in-cloud server(s). In some cases, the local client machine canperform all of the needed parsing and grouping of data in a CFi datastream and then the in-cloud AARMS may not be needed for this process atall and can simply pass the already parsed and grouped CFi data streamto a selected DLUX for further processing (for identifying the one ormore topic nodes that score highest relative to the topic hints providedby the CFi data stream). For each pulled CFi (or parsed and grouped dataobtained from a plurality of CFi's) of the current processing round, thetopic hints or clues in the CFi's are correlated against hint-to-domainprobability factors provided in the user's profiles (e.g., in the user'sCpCCp and/or DsCCp and/or knowledge-base rules sets provided therein) instep 423 c. Probability-of-match scores are computed and assigned foreach CFi's hint group relative to the likely domains that associate withit. After all recently pulled CFi's are looped through for purpose ofidentifying the most likely current domain, the formed list of domainsis ordered in step 423 c so as to list the most likely domain at the topof the list. Scoring may be performed with aid of knowledge-base rulessets as will be detailed below.

At step 424 a, the formed list of likely domains is processed and againfor each of the recently parsed and grouped hint data sets (from therecently pulled CFi's), a machine-implemented determination is made asto which topics under each of the more likely domains is a more likelytopic (or subtopic, etc.). Depending on the targeted degree of topicsameness that was established in steps 421-422, the amount of work donein the topic loop (whose head is step 424 b) will vary. For each pulledCFi(s) data group of the current processing round, the topic hints orclues in the CFi's are correlated against the hint-to-topic probabilityor scoring factors provided in the user's profiles (e.g., DsCCp'sincluding knowledge-base rules set in each such DsCCp) in step 424 c.Probability of match scores are computed and assigned for each CFi datagroup versus its more likely topics (e.g., the top 3 or 5 most likelytopics). After all recently pulled CFi data groups are looped throughfor purpose of identifying the most likely current topics for each, theformed list of topics under the current, likely domain is orderedaccording to score or probability in step 424 c so as to list the mostlikely topic (or subtopic, etc.) at the top of the list.

At step 425 a, the formed list of likely topics is processed from thetop by handing off (step 425 b) to corresponding local DsMS instances inthe data center (e.g., 410) the job of finding a co-compatible one ormore chat rooms (or other online forums) that closely correlate topreferences in the user's CpCCp and/or DsCCp for the kind of chat roomsthe user prefers to be invited into based for example on personalityand/or topic proficiency. Step 426 a determines if the earlierestablished target goals (of steps 421-422) for number of chatopportunities have been met or if a predefined time out has beenreached. If yes, control is passed to step 427 where the found matchesare scored for co-compatibility with the user's preferences (e.g., asexpressed in CpCCp and/or DsCCp) and sorted accordingly with highestscoring ones to be sent to the user's local machine first. Then in step428, all or a highest scoring subset of the corresponding invitationsfor the found chat rooms are downloaded to the client machine as pushedCciv's (e.g., 118 c of FIG. 1A). If no, then at step 426 b it isdetermined if the minimum match goals for the given topic have beenexhausted. If yes, control is returned to step 425 a to investigate formatches under the next most likely topic. If test step 426 b returns ano, then the remaining job for that topic is handed off to a remote DsMSin another data center (optionally with cooperation of it's supervisingAARMS and/or its assigned DLUX) to see if good matching chat rooms caninstead be found in that remote data center. Accordingly, for moreesoteric topics where there may not be enough co-compatible chatpartners joined in a chat room in the current data center (e.g., 410),the search may expand to more and more remotely located data centers(e.g., 420, etc.) in search of a chat room and/or chat partners thatrespectively is or who are co-compatible with the preferences of thecurrent user. Each remote DLUX may begin executing from step 423 viapath 426 d where the target values are current ones rather than initialones established in steps 421-422. Thus, if target values are down tozero, the exit is made via step 423 x. The remote exit via 423 x returnsto step 426 a of the client-servicing data center. Once the targetedgoals are met (or partially met if they cannot be fully met in theallotted time out), the corresponding invitations are downloaded to theclient machine in step 428. The local DLUX is then ready to receive anext task from its supervising AARMS.

One machine-implemented process that may be used for scoring domains(e.g., 423 c) or topics (e.g., 424 c) or other potentially matchablenodes (see FIGS. 4B and 1C) proceeds as follows:

Domain Scoring Step 1: It is possible for a user to be looking atcontent that provides essentially no useful hints as to the domain mostprobably on the user's mind. For example, in FIG. 3A the user may havean open file window like 320 where the file name and/or the file'slocation in the local file directory provide no hints as to domain ortopic and the data being focused upon in the file is equallynondescript. Yet another example is one where the URL of the web page(e.g., 317) the user is focused upon is a one time nondescript one(e.g., a cgi database serve number with no meaning) and the focused upondata is also nondescript. In such cases, best guesses as to what domainsare most probably on the user's mind now can rely on past trendinghistory. What domains have historically been the user's favorites? Alist of such domain identifications may be stored in the user's rootDsCCp such as in column 183 of FIG. 1C. The data may be organized as adatabase table (e.g., Table 1 below) that is sortable according toinitial scores given to each of the domains based only on historicaltrends and without accounting for any additional hints (clues) that mayjustify bumping the score up or down.

Table 1 roughly parallels major row 191 of FIG. 1C while providing someadditional insights. As seen in the third column of database Table 1,each of N domains recently and/or routinely accessed by the user (whereN is predetermined number such as 5, 10, etc. that can vary based on forexample whether the user is a premium subscriber or other, how long theuser has used the system, etc.) has an initial score stored therein. RowID and score need not be correlated. Some domains may share a sameinitial score. When new users join the system, in one embodiment, theyare assigned a stereotyping or template DsCCp where the N entries (e.g.,where N starts off with say 5 most probable domains) are pre-formulatedfor them based on a short questionnaire they fill out. The initialscores may be all the same at the start (say a score of 100, which is anarbitrary number here). Then as the new users begin using thematch-making and invitations-generating system (MM-IGS), trending datais collected about the new users. For example, how often on average perday, week or month do they accept invitations to, or otherwise enterinto chat rooms belonging to the given domain? For how long has thisaveraged usage rate been going on; the last few days, last few weeks,last few months, years? How long has it been since they last used thedomain? In exemplary Table 1, each filled in row has a pointer(tPointer) in the fourth column pointing to where the correspondingtrending history is stored for that user and that identified domain.(Incidentally it need not be a system level domain as shall be explainedlater. For the moment assume it is a system level domain.) Periodically,trending update service modules in the system automatically crawlthrough the collected data and the root DsCCp's of users to determine ifthe initial scores (column 3) for user's favorite domains (as listed inthe user's Table 1) need to be updated. For example, say that user Samhas been highly active in the Finance.002 domain for the last 10 years(but not in the recent month) and thus that row had gotten a score of+100. However, in the last 6 months, Sam has been becoming increasinglymore active on a daily basis in the Politics_(national) domain (row 1)and accordingly, the trending update service modules has promoted theinitial score for row 1 to +100 and had demoted the initial score forrow 1 to +95. If Sam had been equally active in both domains, then eachmay have had an initial score of +100; this indicating that all otherthings being equal, Sam is just as likely in a current time period to bethinking about the Finance.002 domain as he is about Politics_(national)domain when focusing intently upon nondescript content.

The amount that the trending update service modules increase or decreaseeach initial score is a function of a system stored initial scoreadjustment algorithm, where the latter may take into account varioustrending factors including how active the user has recently been in thatdomain and how far back in time the user's preference for that domaingoes. In one embodiment, the system may hold in storage a plurality ofstandardized or template adjustment algorithms for adjusting initialdomain scores where the respective different algorithms are respectivelyused at different times of day, week or for other predeterminedcircumstance. For example, one or more of the conditionally selectabletemplate adjustment algorithms may include a subroutine that accountsfor the condition that, just because Sam has in the last 6 months becomeintensely interested in Politics_(national), that factor does nottotally erase the effects of his continued and persistent interest overthe previous last 10 years in the Finance.002 domain (row 2). While thetrending update service modules may have rapidly elevated thePolitics_(national) domain (row 1) from a score close to zero (or even anegative initial score) to one being the highest current score (e.g.,+100), the adjustment algorithm(s) did not as rapidly demote the initialscore of the Finance.002 domain in view of the inertia of its longhistory of frequent past usage even though Sam may have been neglectingthat domain as of late. After the current political election cycle ends,it is likely that Sam will return to having Finance.002 as his mostfavorite domain. The algorithm(s) model that likely behavior and adjustinitial scores accordingly. The specific adjustment algorithm(s) usedfor initial score adjustments may vary from system to system, datacenter to other center, over different time periods and/or from user touser so as to account for short-lived fads in certain topics and thelike that may temporarily sweep a system-served region. In oneembodiment, premium subscription users may have personal knowledge-baserules sets that control how the trending update service modules increaseor decrease their initial scores and the premium users may be allowed tofine tune these update controlling rules.

As may be appreciated from above Table 1, Sam's list of favorite domainsis longer than the initial 5 domains his template DsCCp (not shown)listed when he first joined. Since then, the trending update servicemodules have not only automatically figured out what specific domainsare Sam's top N (e.g., N=10, not all shown), but the trending updateservice modules have automatically adjusted the initial scores for thosedomains, removed some initial domain names, added some new ones all inview of Sam's recent trending histories for the domains now listed inTable 1, which histories are respectively pointed to by tPointers 1through N of the fourth column of Table 1. A word is in order here aboutwhat the word “domain” means in the context of Sam's Table 1. It shouldbe apparent from FIG. 4B that domain and topic nodes are substantiallythe same except that domain nodes (e.g., 450, 470) are categorized asbeing situated directly under the data center root 402 (and radiallyclose to the origin in the polar topic space of FIG. 6) while othertopic nodes (e.g., 460, 480) are categorized as being situated under atleast one non-root node such as a domain node (and being positionedradially further away from the origin in FIG. 6). It should be apparentfrom FIG. 4D that through a voting process, a topic node can be promotedinto becoming a domain node at a given one data center or at all datacenters in the networked system 400 (FIG. 4A). Additionally, systemadministrators and/or voting users can cause new domain nodes to beadded on a data center-by-data center basis or on a system-wide basis aswell as demoting certain less popular old domains to a topic status oreliminating them entirely if they had not been accessed for a long time.Accordingly, it may be appreciated that there can be different kinds of“domains” including those that are recognized as being a domain on asystem-wide basis and those that are recognized as being a domain onlywithin a given one or more data centers. The term domain serves as anavigational convenience (for example, indicating how close to theorigin the topic node is in a given topic space). It's the first nodeafter root that a navigator might point to while navigating toward adesired target node (which could be the domain node) in a given datacenter. Thus the concept of a personal domain can be appreciated asbeing a shortcut to a target node that an individual user often refersto with such frequency that for that user, the topic node might as wellbe a domain node. By way of example, assume that user Sam is an avidbeliever in Anthropomorphically-induced Global Warming (or AGW as itsfollowers refer to it). Perhaps for other people AGW is categorized as asubtopic under the science fiction category, but for Sam, assume it isan incontrovertible fact that he thinks about every day and for which hesees many subtopics. If this is the case, Table 1, column 2 can list AGWas being a personal domain of Sam's even though other people in Sam'shome data center may not see it as qualifying for domain status. Thepoint is that the “domains” listed in Table 1, column 2 and pointed toby associated Domain node ID'ing objects can be system-wide domains, ordata center only domains or personal domains of the individual user(e.g., Sam). The Domain node ID'ing object (e.g., a node ID tag such asD273.87 of row 2, column 2—or it could be navigation pathway to the nodefrom root or other starting point) is a system recognizable shortcutthat can be used to quickly jump to or navigate to the intended domainor topic node irrespective of where it is in the hierarchy tree of FIG.4B and without having to resort to a node name to node location lookuptable. Accordingly, Finance.002 may be a personal domain of Sam's ratherthan a system wide domain and in the context of Table 1 that makes nosubstantial difference. Although not shown, in one embodiment; one ormore rows of Table 1 may store coordinates (e.g., polar coordinates)pointing to a specific point, or area or shadow cone in a predefinedtopic space such as that of FIG. 6. Topic hints in that row may be usedto link to whatever topic nodes happen to currently occupy the specificpoint, area, or shadow cone in the predefined topic space. In otherwords, some rows of Table 1 may specify a target node without knowingthe target node's name or ID and instead by simply pointing to a regionin topic space where that node is expected to be found.

Incidentally, it may be appreciated from the above that processing of alookup assisting, relational database table, like above Table 1, canconsume significant system resources. On the other hand, there may becertain circumstances under which resort to the lookup assisting table(e.g., Table 1) is a complete waste of time. For example, a given user(e.g., Sam) may have a respective habit of behavior where, it is 9:30 AM(EST) and it is a day on which the New York Stock Market is open, theonly topic he has on his mind is the Finance.002 topic. It would be awaste of system resources and energies to lookup Table 1 and startcompetitively scoring all the possible domains and/or topics, subtopics,etc., that Sam may be thinking about. Instead, an overriding and earlierexecuted rule in the given user's DsCCp knowledge-base rules set 195might read as follows: 0. IF Time_of_Day is in range 9:25 AM (EST) to10:05 AM (EST) AND Day_of_Week=Market_Open_Day, THEN Ignore ScoringTable 1 and Return Matching Domain Set as Finance.002. Special andearlier executed rules for overriding the entire lookup assisting table(e.g., Table 1) or excluding from consideration certain parts of it(certain rows and/or columns) may use a variety of triggeringconditionals including for example, time of day, week, month or year;current surroundings of the user (e.g., work versus home, alone versusaccompanied by others); the type of primary client machine being used(e.g., small screen PDA as opposed to wide or multiple screens homedesktop computer), and so on. System resources can be significantlyconserved by use of such selective override or exclusion rules.

Still referring to Table 1, it may be may be appreciated that theautomated trending update service modules have also automaticallydetermined what Sam's top M web page URL's were under each domain andtheir order of preferential visitation to such URL's by Sam. Thesetable-recorded URL's are the ones that Sam most often referred to duringhis PEEP-defined normal time-stretches when accepting invitations to thecorresponding domains (where M is a system specified number such as 3,5, etc. and PEEP-defined normal time-stretch can vary fromdomain-to-domain). Note that the entry in row 8 of column 5 includes notonly the name of a URL called More.com (a fictitious alias) but also apointer (ptr2rules.4_more.com) which points to one or moreknowledge-base rules associated with that URL and the domain of its rowin Table 1. In fact each URL listed down column 5 of Table 1 can have arespective “pointer to rules for” (ptr2rules.4_) it recorded in Table 1or otherwise logically linked to that URL's listing in Table 1. Thereason for having such pointers will explained shortly.

Still referring to Table 1, it may be may be further appreciated thatthe automated trending update service modules have also automaticallydetermined for each listed domain what the top Q search keywords were(and their order of preference by Sam as shown in the sixth column)where these table-recorded search keywords are the ones that Sam mostoften used to during his PEEP-defined normal time-stretches whenaccepting invitations to the corresponding domain (where Q is a systemspecified number such as 3, 5, etc.). The trending update servicemodules have also automatically determined for each listed domain whatthe top P meta-tags were that were present (and their relativefrequencies of presence as shown in the seventh column) where thesetable-recorded meta-tags that were most frequently present (embedded)ones in the focused upon content that Sam was browsing during hisPEEP-defined normal time-stretches when accepting invitations to thecorresponding domain (where P is a system specified number such as 3, 5,etc.) Table 1 may of course have more columns that list yet otherattributes which are most frequently associated with the respectivedomains and optionally pointers to knowledge-base rules sets associatedwith those attributes.

Domain Scoring Optional Step 2: The initial scores listed in column 3 ofTable 1 are not necessarily the final scores allocated to the listeddomains when performing a domain lookup. They will be final if there isno other useful hinting information available for improving the guess asto what topic the user has in mind. Assuming however, that there is someform of usable hint data in the CFi's recently pulled from Sam's localmachine(s), the domain lookup process will use the initial scores merelyas a starting point for generating running scores that modulate up ordown relative to the initial scores (or don't change) based onadditional hinting information provided by CFi's uploaded over stretchesof time corresponding to Sam's PEEP-defined normal time-stretches forthe respective domains (the time-stretches may different, for exampleonly 2 minutes to look at today's comic strip, but 10 minutes to studytoday's stock market results). In one embodiment, time for re-scoring islimited to a predefined number (can vary if user is a premium user). Inother words, whatever the running scores are when the time limit runsout, those scores are taken as good enough competitive indicators ofwhat is likely on the given user's mind. In such a system, the scorechanging computations with potential for larger score changes should berun first and those with finer refinements of score run later. In oneembodiment, the initial list of N domains provided by Table 1 and underconsideration (if not selectively excluded out) by the domain lookupprocess may increase or decrease as a result of execution of variousknowledge-base rules including rules that can exclude from considerationsome of the domains listed in the user's Table 1. In other words,although Politics_(national) is listed in Table 1 as having the highestinitial probability of being on Sam's mind, certain hints collected fromrecent CFi's may cause that domain to be excluded from furtherconsideration and when this happens, the system can stop keeping arunning score for such an already excluded domain. In forming therunning scores for non-excluded domains, the domain lookup processcombines the initial scores assigned to Sam's top N domains (if notexcluded, and also to scores of additional domains which may be broughtinto consideration by knowledge-base rules) with score increasing and/orscore decreasing factors to thus form current running scores (whichscores can dynamically change due to new CFi's being further uploadedinto the cloud in, say, the next 30 seconds).

More specifically, suppose for example that Sam visited the WSJ.com webpage in the last 2 minutes. His initial score of +95 for the Finance.002domain may be automatically increased to +105 as a result. But supposethat Sam also visited the NYTimes.com web page in the last 3 minutes.His initial score of +100 for the Politics_(national) domain (row 1) maybe automatically increased to +108 as a result. Similarly if any of thetable-listed favorite search keywords are found to have been used in thelast X minutes (X being variable on a domain by domain basis), then therespective running scores may be automatically increased or decreasedfor each occurrence by appropriately weighted amounts in response.Similarly if any of the table-listed frequent meta-tags are found tohave been present in the last Y minutes in content Sam was intentlyfocusing upon (Y being variable on a domain by domain basis) then therespective scores may be automatically increased or decreased for eachoccurrence by appropriately weighted amounts in response. The amounts ofchange of each running score may be a function of a system storedrunning score adjustment algorithm, where the latter may take intoaccount various trending factors including those operating on auser-by-user basis, on a data center-by-data center basis and/or on thebasis of time of day, of week, of month, etc. As such the preliminaryrunning score adjustment algorithm used for such first round adjustments(there may be further re-scoring rounds as discussed below) can varyfrom system-to-system and there is no specific embodiment discloseablehere for better empowering artisans to carry out the same. Note thatweighting of score adjustments can take into account the intensity offocus (e.g., emotional engagement) that Sam exhibits in conjunction witheach CFi provided data point (e.g., URL, keyword, meta-tag) and thusweights need not be purely linear but can instead be products of anintensity of focus score multiplied by an occurrence-of-hint score andmultiplied by a factor representing preference position in an orderedlist of table-specified hints. More specifically, because the keywordhint, “soccer” appears first in the list of favorite keywords of row 3(Sports) and “game” appears third, detection of “soccer” will generallytend to increase the running score for the row 3 domain (Sports) morethan detection of “game” as a recent keyword. Moreover, note that thekeyword, “game” appears also in row 4 of Table 1 (for Poker). So if theonly useful hint data pulled from recent CFi's is the search word,“game”, the running scores of the row 3 and row 4 domains would both beincreased by roughly the same amount and the relative competitivescoring positions of the two domains, if both are not excluded fromconsideration, would generally not change.

Domain Scoring Optional Step 3: As mentioned above, there is only somuch improvement attainable in guessing at a user's current domain ofinterest and the user's current topic of interest under that domain byusing the 2 dimensional table approach of above Table 1. Firstly, thereis a practical limit as to how large the number N can be for the numberof most favorite domains tracked for every user by a table such asTable 1. Secondly, no matter how large N is, there can still be anobscure domain that the user (e.g., Sam) currently has on his mind andis not yet listed in his top N domains in Table 1. So if the domainlookup process relied only on scoring the top N domains of Table 1, thesystem may more often than desirable, invite Sam to an incorrect chatroom because the system did not take into account the possibility thatSam is thinking about a domain not yet listed as the top N domains thatSam frequents. Thirdly, the system may waste time, energy and resourcesin conducting unnecessary scoring activities under variouscircumstances. Suppose for example, it is determinable that 99% of thetime during business days (e.g., Monday to Friday) and between the hoursof 9 AM and 5 PM, a given user such as Sam does not think about thedomains of above Table 1, rows 3-5 and rows 8-N. In such as case itwould be wasteful to compute scores for those domains during the statedtime periods. A simple database having only a structure like Table 1cannot conventionally account for all such possible variations. On theother hand, a knowledge-base rules set such as 195 of FIG. 1C can bestructured to provide for a large number of unusual contingenciesincluding limiting the extent to which the contents of Table 1 (or itsequivalent) are considered—versus being automatically excluded fromconsideration—during different time periods and/or when the user (Sam)is located in different surrounding environments (e.g., work versushome). More specifically and by way of example, knowledge-base rules set195 may include a conditional rule that controls which of the N domainslisted in column 183 of FIG. 1C are excluded from scoring underdifferent circumstances. An exemplary control rule may read as follows:IF Time_of_day:=Business_Hours AND Day_of_Week:=Business_Day ANDSurroundings:=Workplace, THEN Exclude from System_Domain_Scoring, rows3-5,8-N of Table 1 AND Set Final_Score:=0 for rows 3-5,8-N; ELSE IFDay_of_Week:=Weekend AND Week:=Poker_Tournament_Week, THENIncrease_Score of domain row 4 by +50 points; ELSE IF Time_of_day:=>7 PMbut <12:01 AM AND Surroundings:=Home THEN UseSystem_Scoring_Template_(—)9 for first round re-scoring of Domains.

As seen from the above pseudo code, the DsCCp knowledge-base rules set195 of one embodiment can control how scoring is performed under variousconditions including time of day and location from which the user isoperating. Additionally it should be mentioned that the initial list ofdomains or topics considered can be expanded beyond that provided for byTable 1 through use of consideration-expanding rules, such as forexample: IF Time_of_day:=After Work AND Surroundings:=Home, THEN ADD tolist of nodes to be scored: <begin list>My_Hobby with an initial scoreof 88 <end list>. This has the effect of dynamically expanding Table 1.Accordingly, entirely different initial domains and correspondingdifferent scoring algorithms may be selectively executed in response tovarying conditions so as to more flexibly determine what domain a givenuser is probably thinking about in view of uploaded CFi data includingCFi data that indicates where the user is located and what the time wasfor respective ones of the collected pieces of topic hint data andemotional state indicating data.

Moreover, if certain combinations of external events take place, theknowledge-base rules set 195 may include one or more conditional rulesthat cause esoteric domains to be added to the list of domains underconsideration and thus being scored competitively against other domainsunder consideration. For example, set 195 may include the rule: IFTime_of_Year:=International World Soccer Cup Semifinals or Finals THENAdd Sports.100 domain to Domains_scoring_List AND Set Initial_Score ofSports.100 domain to +200 AND Set End_of_Range of Business_Day to 3 PM(rather than usual 5 PM). Accordingly, it is seen that a soccerenthusiast may command the system to accommodate his esotericpreferences on an individualized basis, cut the definition of hisroutine work day short and add a special domain into the competitivepool when the International World Soccer Cup Semifinal or Final gamesare taking place. Additionally, as mentioned above, automated trendingservices may automatically readjust a user's knowledge-base rules set tomore accurately reflect his actual behavior as opposed to his declaredbehavior. For example, although Sam said he would work until 3 PM duringsoccer season, in fact for the last 3 years he had run home at 2 PM towatch the games. In one embodiment, the trending services would spotthat and automatically modify the above soccer cup handling rule to endthe business day at 2 PM rather than 3 PM as Sam had said. This way thesystem will be serving Sam according to his actual behavior rather thanhis declared behavior.

To summarize part of what is taught by the above, in accordance with oneembodiment, the knowledge-base rules set 195 in the user's currentlyactive DsCCp (106 h.1) has a first set of one or more rules that controlwhich of a limited number of N′ domains will be actively considered andscored (as opposed to being excluded under current circumstances, wherethe limited number N′ can be greater than N as well as less than the Nof Table 1, e.g., N=10) and which scoring algorithms will be used forperforming such first round or later round re-scorings. These one ormore scoring algorithm control rules are executed before any of theactual first round or later round domain re-scoring algorithms areexecuted. (The later round domain re-scoring algorithms will take intoaccount synergisms of occurrence such as, IF Snapshot_of_contentbeing_focused_upon includes WORD1 Within_(—)5_words_of WORD2, THENIncrease_Score_of (Domain 6) by +70.)

Parsing, grouping, cross-linking and further weighting of CFi-supplieddata samples prior to domain lookup: Referring briefly back to FIG. 2A,recall that streams of CFi packets can be uploaded to the match-makingand invitations-generating system (MM-IGS) from a variety of CFigenerating devices and that each CFi packet or record can contain pluraldata samples of different kinds (e.g., snapshot of content, biometricdata, etc.) rather than just one. More specifically, a given one CFirecord may contain biometric data indicating that the user is becomingincreasingly agitated about content he or she focused upon about 2minutes ago. At the same time, the given one CFi record may contain newkeyword data about an unrelated search the user performed just 30seconds ago. To work properly, the system should link the biometric dataindicating agitation to content that was identified in a CFi having atime stamp of about 2 minutes earlier than the time stamp of the currentCFi. The system should not link the unrelated search terms in thecurrent CFi to the content identified in the older CFi. In order to knowhow to do so automatically, the system has to learn how this particularuser (e.g., Sam) tends to behave. Some of the user's behavioral trendingdata is provided in the user's PEEP record (see FIG. 1E). For example,the user's PEEP record may include a knowledge-base rule stating to theeffect: IF User_State:=Agitated_Type_(—)1 THEN Time_of_CausalContent:=−2 minutes ago. The system can then automatically determinethat it needs to logically link the agitation state reported in thecurrent CFI to the focused upon content reported in the CFi received 2minutes earlier.

However, the user's PEEP record usually does not indicate how he behaveswith respect specific domains. In one embodiment, parsing, grouping andweighting of CFi-supplied data samples is a task that is split betweenthe AARMS module that initially receives the CFi streams of user X andthe DLUX module(s) to which the AARMS forwards the job for completion.The AARMS will handle the processing of the emotional state portion ofthe parsing task so that it can then prioritize domain lookup tasksaccording to how emotionally involved the user appears to be with thatcertain content. However, some of the parsing and grouping task callsfor knowledge about the user's Domain-specific behaviors and thisinformation is generally stored in the user's DsCCp records, where thelatter are generally processed by the DLUX service module to which theAARMS hands off completion of the domain determination task (and alsothe topic lookup task). So in the example given immediately above, theAARMS would know to create a data grouping or cross-referencing linkbetween the content identifier in the CFI that was time stamped 2minutes earlier and the emotional reaction data supplied in the currentCFi. However, the AARMS would not know how to properly parse and groupthe new keyword data that just came in and happens to be part of anunrelated search because information for parsing of such domain specificdata is typically contained in the DsCCp rules 195 rather than in thePEEP rules 199. So the AARMS hands off partially resolved streams of CFidata (partially cross-linked CFi sample point data) to the DLUX moduleand the latter completes the parsing and grouping task based on theuser's current DsCCp record 106 h.1. Scanning down column 6 of aboveTable 1 for example, the DLUX can determine what search keywords mostprobably correlate with what domains. The DLUX can also determine whatthe more probable domains are that the content from 2 minutes agobelongs to. If the two lists of domains do not overlap, the DLUX canconclude that the keywords of the current CFi are not to be grouped with(cross linked with) the content of the CFi from 2 minutes ago. Whilethis is an all or nothing example, it can be appreciated that for grayzone situations, the DLUX assigns grouping weights or probability ofgrouping factors to different pieces of incoming sample data. Theagitated emotional state of the current CFi and the 2 minute old contentof the previous CFi may have a strong cross-grouping factor linking thetwo data items while the less certain plurality of recent keywords mayacquire a weaker cross-grouping factor between itself and the 2 minuteold previous content. Since the agitated emotional state reported in themost recent CFi cannot possibly be a delayed outcome of the currentlyreceived search terms, the cross-grouping factor between the recentkeywords and the agitated emotional state will generally be set to zero.In this way a historical record of events and underlying cross-groupingfactors is built up by the DLUX. The cross-grouping factors function asweights that emphasize cross effects between more clearly linkedtogether data samples and deemphasize cross effects between less clearlylinked together data samples as they are parsed out from the streams ofCFi's uploaded into the cloud 150. One way of thinking about thisprocess is by analogy to a double sided data recording tape whereobserved data is recorded in chronological sequence on one side of thedouble sided tape and hypotheses about interrelations between theobserved data points are recorded on the other face of the datarecording tape.

With parsed and cross-linked sample data points in place, the DLUX is ina position to further weight content-identifying data points as afunction of the strongly cross linked topic hints that go with them andas a function of the more strongly cross linked biometric data itemsthat also go with them. More specifically, for each “known” URL or alikecontent identifier that appears in the fifth column of above Table 1 andfor the N′ domains that are under consideration and being scored thereshould be a corresponding cross-correlation rule in area 195 of theDsCCp that increases or decreases the running scores of the N′ domainsunder consideration according to cross-correlation of data items. Forexample, IF URL:=NYTimes.com AND Cross_link_to emotional data:=Strong,THEN Increase_score_of (Domain of row 1, if not excluded) by +20,Increase_score_of (Domain of row 2, if not excluded) by +5,Decrease_score_of (Domain of row 3, if not excluded) by −10,Decrease_score_of (row 4 (Poker), if not excluded) by −20, etc. In otherwords, for each CFi data sample or Value uploaded from the user'sreporting device(s), first it will be determined what the type is of thedata sample (e.g., URL or alike content location identifier, keyword,meta-tag etc.) and also whether the uploaded data point sample is atable-known one already stored in Table 1 (or an equivalent thereof). Ifyes, then in a pointer layer (not fully shown, see ptr2rules4_) thatshadows the contents of Table 1 there will be pointers to correspondingscoring rules. For example, logically linked with the “NYTimes.com”entry in column 5, row 1 of above Table 1 there will be a pointer to oneor more scoring rules like the immediately above, IF URL:=NYTimes.comAND . . . rule. The associated rule for the known Table-included samplepoint will be applied and the N′ domain scores under consideration willbe adjusted accordingly.

-   -   Treatment of Nondescript Common Words: If one or more        CFi-supplied sample point data items is not in Table 1 but is        instead stored in another table of predefined common nondescript        words like “the”, “of”, etc., a separate rule for handling such        common nondescript words will be executed where typically the        scoring action is to ignore the nondescript words and not change        the scores of the N′ domains under consideration in response. Of        course, there can be esoteric exceptions to this general rule        and such exceptions will be expressed within the rule that        handles the listed and generally common nondescript words.    -   Treatment of routinely opened Known Locations. Typically, when a        user first launches his browser (e.g., FireFox™, Internet        Explorer™, etc.) the browser may have an initialization script        that it automatically executes upon launching where it downloads        one or more default start pages (i.e. Yahoo™, MyYahoo™, MSN™,        GoogleNews™, iGoogle™, etc.). In such a case, because user        activity did not directly and intentionally cause the loading of        these routine pages, the URL's and other topic hints found on        these pages will generally not be indicative of the user's        current topics (or domains) of substantial interest. The        knowledge-base rules set 195 of the current DsCCp 106 h.1 (e.g.,        the user's root DsCCp) may accordingly include a special        processing rule for web pages that are initially or routinely        downloaded shortly after launch of the browser. For example, IF        Time_after_browser_launch <2 minutes multiply uploaded sample        data points thus far by an importance de-weighting factor of        0.1. In an alternate embodiment, the de-weighting factor        assigned to such launch associated data points (e.g., URL, Meta        tags and snapshot content) can be a weight of 0. The point here        is that some web pages should be automatically ignored so that        time and machine resources are not wasted attempting to do        domain lookups for them.    -   Treatment of different types of CFi-supplied data points        (Treatment by CFi Value Category): Some CFi-supplied data points        can be of greater importance in determining likely domain of        interest than others. For example, if the user entered a set of        keywords into his or her search engine 5 minutes ago and then        spent the last three minutes intently studying content in a URL        found by the search engine, that can be taken as highly        supportive of the hypothesis that the keywords of 5 minutes ago        strongly cross-correlate with the topic of interest currently on        the user's mind. A corresponding treatment rule in        knowledge-base 195 may read as follows: IF        URL_of_strong_interest follows within 7 minutes after keyword        search THEN apply importance weighting increasing factor of 1.8        to the keywords. Thus, Search Term Values submitted by the user        as part of an explicit search request are taken as highly        indicative of what is on the user's mind because these are        values that the user has explicitly expressed an interest in.        The specific knowledge-base rule(s) used to more heavily weight        such user expressed keywords can vary from user-to-user and from        one surrounding environment or time to the next.    -   Treatment of extremely unique file, page or other content        addressing information—Some URL addresses are relatively        non-informative of what is on the user's mind because they        connect to a broad topic portal, say Google.com™. As such, when        a CFi provides such a broad topic hint (be it to a widely used        internet page or to a file directory that contains files        directed at a sundry of random topics or another form of content        addressing information whose covered topics are non-unique)        there is not much that the domain lookup process can do with        this information. On the other hand, some URL addresses or other        content addressing information may be extremely unique and thus        tightly coupled to one specific or to a fairly limited group of        domains or topics. Accordingly, in one embodiment, a list is        stored for each user of such corresponding and tightly coupled        URL's or other content addressing information and the one or        more small number of topics or domains that they tightly couple        to when the given user is involved. An importance-increasing        factor is then applied to such listed addresses when they show        up in the CFi stream and the list of unique URL or other        addresses is consulted by the domain lookup process when one of        these addresses is present. Such unique addresses may be        collected from the user's web browser, his FTP client,        pod-catcher, etc. These addresses may be in the form of a URL        for a web page, an FTP site address and/or the name of a file        being downloaded or in the form of a podcast's URI, or any other        type of unique combination of data that points to the content        the user is interacting with (viewing, downloading, listening        to, etc) where the corresponding set of associated topics or        domains is relatively narrow (e.g., 5 or less)    -   Treatment of extremely informative Meta Tags: As mentioned        above, meta-tags are typically hidden codes embedded in web page        content (e.g., HTML or XML content) or in podcast content (or in        the source page or home page from where the podcast stream or        other stream, i.e. RSS was obtained) and these often indicate        what the author of the content believed to be significant        descriptors of the corresponding content. Some meta-tags can be        rather broad in nature and thus not informative enough regarding        what is likely on the user's mind (e.g., Sam's) when they        connect to content having such meta-tags embedded in it. On the        other hand, other meta-tags can be extremely unique and thus        tightly coupled to one specific or to a fairly limited group of        domains or topics. Accordingly, in one embodiment, a list is        stored for each user of such corresponding and tightly coupled        meta-tags (the more often seen ones) and the one or more small        number of topics or domains that they tightly couple to when the        given user is involved. An importance-increasing factor is then        applied to such listed meta-tags when they show up in the CFi        stream and the list of unique meta-tags is consulted by the        domain lookup process when one of these meta-tags is present.    -   Treatment of potentially informative Web Page heading fields and        the like. As known to those skilled in HTML or other web page        defining languages (including XML, CSS etc.), certain content        may be embraced between <<Hn>> and <</Hn>> tags, where n is a        heading level number. Other page defining languages may use        stylesheet references where the referenced style sheets may        include emphasis commands for style like Title, Big, Bold, etc.,        and these are often used to indicate important parts of the        to-be-displayed web page. In one embodiment, an        importance-increasing factor is automatically applied to such        content that is emphasized by heading braces or the like where        the importance increasing factors may vary as a function of        heading level (n) and/or as a function of how many style        modifiers are applied to the content.    -   Treatment of probably uninformative Web Page content formatting        codes: As known to those skilled in HTML or other web page        defining languages, certain content may be embraced between        formatting codes calling for rudimentary bolding or in        italicizing of such content. This does not routinely mean the        content is important. As such, in one embodiment, no adjustments        are made to the weight of such routinely formatted content.    -   Adaptive Learning: As users interact with the match-making and        invitations-generating system (MM-IGS), automated trend tracking        services of the MM-IGS will keep track of the invitations which        the users accept and of the CFi data streams and weights        attached thereto that led to successfully accepted invitations        as well as perhaps to positive interaction with the respective        chat room. Positive feedback scores will be generated for        successfully accepted invitations and the respective ways in        which their CFi data streams were processed by the system.        Negative feedback scores will be generated for declined        invitations and the respective ways in which their CFi data        streams were processed by the system; particularly if the CFi        processing had resulted in giving a relatively high match score        to the target chat room. (It is more understandable why a user        may have declined a lower scored match and thus no negative        feedback will be generated for such.) Over time, success and        failure patterns will emerge. These feedback patterns can be        used to automatically adjust how the stream of CFi values        uploaded from the client machines are later processed (e.g.,        what importance enhancing weights are attached to certain kinds,        how CFi data spread over time is grouped together, which        re-scoring algorithms are applied, and so forth). Here is an        example regarding a user who is interested in soccer:

The CFi stream received from the user's client machine contains theheadlined or otherwise emphasized content words: “Football”, “Referee”,and “Gialloblu” (where the latter is a nickname of an Italian soccerteam in Parma). In response the match-making and invitations-generatingsystem (MM-IGS) produces a plurality of chat opportunities which arereturned to the user's client machine in the form of severalhighly-scored invitations. The user accepts a particular one of theofferings. The accepted invitation is to a chat room that not onlystrongly correlates with “Football”, “Referee”, and “Gialloblu”, butalso with additional keywords, “Soccer” and “Parma”. (These associatedkeywords may be stored in region 465 a for example of the node (e.g.,460 of FIG. 4B) which the accepted chat room (e.g., 469) resides under.The system can then responsively build a more detailed cross-correlationin its database(s) as between the soccer infatuated user (e.g., Sam) andthe submitted first three emphasized content words: “Football”,“Referee”, and “Gialloblu” and the node-stored common keywords, “Soccer”and “Parma”. The database entries may appear as follows:

-   -   Football submit count=1    -   Soccer hit count=1    -   Parma hit count=1    -   Referee submit count=1    -   Soccer hit count=1    -   Parma hit count=1    -   Gialloblu submit count=1    -   Soccer hit count=1    -   Parma hit count=1

Later the same user's client machine submits a CFi stream containing theheadlined or otherwise emphasized content words: “Football”, “Contract”,and “Cagni” (where the latter is a manager of an Italian soccer team inEmpoli). Once again, the match-making and invitations-generating system(MM-IGS) produces a plurality of chat opportunities which are returnedto the user's client machine in the form of several highly-scoredinvitations. The user accepts a particular one of the offerings. Theaccepted invitation is to a chat room that not only strongly correlateswith “Football”, “Contract”, and “Cagni” but also with additionalnode-supplied keywords, “Soccer” and “Empoli”. The system will nowupdate its database entries so they appear as follows:

-   -   Football submit count=2    -   Soccer hit count=2    -   Empoli hit count=1    -   Contract submit count=1    -   Soccer hit count=1    -   Empoli hit count=1    -   Cagni submit count=1    -   Soccer hit count=1    -   Empoli hit count=1    -   As can be seen, the correlation for this user between the        Football submit count and the Soccer hit count has strengthened        (2 for 2). Assume that as this same user continues to interact        with MM-IGS, the submit counts for “Football” keep going up and        corresponding hit counts for “Soccer” continue to increase in        pace. The higher the number of submits is and the closer the        Hits/Submits ratio is to one, the greater is the associated        correlation between the content word Football and the keyword        Soccer for this user. Note: in this section that submit counts        are referring to CFi content values submitted by user which also        resulted in acceptance by the user of a corresponding chat        invitation. CFi values submitted by clients that do not result        in invitation acceptance, or even in a sending out of a chat        invitation may still be tracked elsewhere as part of the        trending data tracking process but they are not relevant to this        Hits/Submits correlation feature.

By automatically keeping track of the Hits/Submits numerators anddenominators for each user (or premium user), the match-making systemwill be able to implement the following additional rules:

-   -   Low hit count numbers below a predefined threshold are deemed to        be irrelevant and thus meaningless. For example the 1/1        association between “Contract” and “Empoli” is weak for this        user and therefore it will be ignored.    -   Hit counts are deemed to become more significant once they pass        beyond one or more successive threshold settings. When this        happens the correlation between the hit term (e.g., Soccer) and        the submitted data point (e.g., Football) will be automatically        added to a corresponding strong correlations list maintained for        the respective user.

After a sufficiently strong Hits/Submits correlation is added to acorrelations list of same strength correlations maintained for the user,each time the Submit word appears in a CFi input stream from theclient's machine, the not-submitted but cross-correlated Hit word (e.g.,Soccer) will be automatically added to the search terms that the domainlookup process uses. Since the domain lookup process now has a largerlist of different match terms, the likelihood is increased that a foundchat room will more accurately reflect what the user has in mind. Inother words, by tracking Hits/Submits for this user, the system overtime learns to map the user's preferred terminology of “Football” forwhat the broader system node mappings refer to as “Soccer”. Thus even ifthis particular user tends to employ less common words or phrases forthe topics he has in mind, the system over time automatically learnsabout the user's word choice preferences and adapts.

In one embodiment, an importance enhancing weight applied to the addedHit term is a function of its Hits/Submits ratio. For example, if theuser has 5 hits on “Soccer” in response to submitting “Football” 10times, the added hit term “Soccer” would have its importance weightfactored as: (“football weight”*5/10). This type of weighting willensure that more significant Hit terms are given greater weighting thanless well correlated Hit terms.

-   -   Note that within this process, the client submitted match word        (e.g., “Football”) will not be removed from the list of        to-be-matched words. In other words, the client submitted data        value (“Football”) will not be translated into its        cross-correlated system-common term (e.g., “Soccer”). Rather,        the list of to-be-matched words is being expanded in accordance        with the trend-produced cross-correlations. By using this        non-translative technique, it is ensured that the original        user-submitted hint values continue to get through and generate        directly associated chat opportunities. For example if this same        user became interested in the American football team, the Dallas        Cowboys™ and submitted CFi hint values “Football” and “Cowboys”        the to-be-matched words list would be automatically expanded to        “Football”, “Cowboys” and “Soccer”. This submission would likely        result in chat opportunities regarding soccer teams associated        with the name “Cowboys” but it will also likely produce chat        opportunities regarding the Dallas Cowboys™ as well and the user        may then pick from this expanded set of results the chat        opportunity that best reflects his current topic of interest.

In summary, by expanding the list of to-be-matched terms in thisnon-translative way and weighting expansion terms according to observedHits/Submits usage patterns, the system is able to dynamically adapt toeach individual user's style of interacting with the system. The userwill not have to learn to type “soccer” when they are thinking aboutEnglish “football”. Instead, the system will adaptively learn that thisuser is often referring to “soccer” when they submit “football”.

Different scoring techniques for rating domains and/or topics: Referringto step 424 a of FIG. 4C, it should be now apparent that after one ormore of the above techniques is used to identify the more likely ones(e.g., the top three) of the possible domains that the user has in mind,for each of the more highly scored domains, starting with the highest,similar techniques may be used to identify the more likely ones (e.g.,the top three) of the possible topics under each domain. The techniquesused for finding the more likely topics do not have to be exactly thesame as those used to identify the more likely domains.

Here is one possible score generation and score assessment technique:

-   -   Scoring Technique Step 1: Add or multiply the computed        importance enhancing or importance lowering weight for each term        in the list of to-be-matched terms (e.g., including “Football”        and “Soccer”), process the weighted list against each of the N′        domain nodes under consideration and normalize the returned        match value by dividing by the number of total terms in the        compiled to-be-matched list so that to-be-matched lists with        more terms in them do not get an unfair advantage over competing        to-be-matched lists which happen to have fewer terms in them. In        one embodiment, the returned match value is a function of a sum        of match subtotals found for each term alone where the subtotals        are multiplied by their respective importance enhancing or        importance lowering weights and then added together, thus giving        long-winded to-be-matched lists a competitive advantage over        shorter lists.    -   Example: If the compiled list of to-be-matched terms (e.g.,        including “Football” and “Soccer”) contains 10 values, each with        an importance weight of 1, out of which 5 of the list's values        match 5 out of the total of 15 of the domain node's matchable        terms, then the matched to number-in-list ratio is 5 out of 10,        or 50%. Another list of to-be-matched terms may have 4 terms and        all four terms match a prospective domain node, in which case        the matched to number-in-list ratio is 4 out of 4, or 100%.        However this need not be the only score comparing factor. The        second node may have had a total of 20 domain node matchable        terms, in which case the matched to matchable ratio is 4/20 or        20%. On the other hand, for the first node, the matched to        matchable ratio was 5/15 or 33%, which is higher. How these        different ratios are treated in the final analysis can vary from        system to system. In one embodiment, the respective matched to        matchable and matched to number-in-list ratios are added to        thereby give the first node a score of 50%+33% or 83 (not a        percentage) and to give the second node a score of 100%+20% or        120 (not a percentage). In this case the match between the        second list and the second node is rated higher than the match        between the first list and the first node.

MORE HYPOTHETICAL EXAMPLES Example 1

A grouped set of CFi-contained content samples consists of 10 datasamples (to continue with the rating example immediately above) issubmitted to the match-making and invitations-generating system (MM-IGS)because the corresponding user (Sam) just interacted with a popular webportal home page (e.g., MSN.com™ or Yahoo.com™). The 10 data samplesinclude the web page's URL and meta-tags extracted from the web page'sHTML source code. Because such portal web pages have been determined bythe MM-IGS to be commonly accessed as a user's default home page bylarge populations of users, the MM-IGS lists the URL's and/or attributesof such portal web pages in a to-be-ignored list stored within theMM-IGS. In one embodiment, the MM-IGS automatically assigns a 0importance weight to URL's listed in the to-be-ignored list and a 0importance weight to the CFi-contained content samples that are groupedto such URL's. In general users will not be paying any particularattention to content on their default home page even if they stare atthem for a long time, and since 0 importance weights are automaticallyassigned to the correspondingly uploaded CFi's, no domain lookup orrating resources will be wasted and therefore no attempt at creatingchat opportunity matches will occur. Of course, there can be exceptionswhere specific users do want match-making to occur for their defaulthome pages. These exceptions can be handled by specialized DsCCpknowledge-base rules that, for example, translate a to-be-ignored URLstring into a not-to-be-ignored alias which the system recognizes assuch.

Example 2

The same user as in above hypothetical Example 1 opens and stares atanother web page whose URL is not listed on the to-be-ignored list. Onceagain this user activity produces a grouped set of CFi-contained contentsamples consists of 10 data samples including the new URL value. Sincethe URL is not on the to-be-ignored list, the MM-IGS does notautomatically assign zero importance weights to the associated 9 otherdata samples, they retain their original weights (e.g., a defaultweighting of 1) or are upgraded or downgraded in importance byappropriate weight adjustment rules (e.g., if content was braced insideheading tags) and the non-zero-weighted CFi-provided data samples areforwarded to the domain lookup process for further processing.

Example 3

After opening the non-portal second web page, this same user initiates aweb search about 3 minutes later by entering 3 search terms. The user'sPEEP record indicates that such follow up activity within 5 minutes ofhaving opened a non-portal page normally indicates strong topiccross-correlation between the earlier opening of the web non-portal pageand the current search keywords. In other words, the earlier grouped setof CFi-contained content samples consisting of 10 data samples includingthe second URL value are to now be cross-correlated with the 3 newsearch keywords when performing domain lookup. Because the userexplicitly entered the 3 new search keywords (as opposed to other hintdata which was obtained by benign spyware without the user's directparticipation), the match-making system automatically assigns higherweights to the 3 new search keywords and then concatenates them to theearlier weighted 10 data samples. The concatenated combination is thempassed to the domain lookup process for further processing. In summary,these examples show how domain lookups are differently handled based onwhether reference was made to a common or default home page URL whoseassociated sample points are scored low because the user is inferred tobe not paying actual attention to them even if it seems he is and basedon whether the user explicitly participated in generation of some of thecontent samples, in which case the explicitly generated sample pointsare given comparatively higher weights than sample points that areautomatically gathered by the benign spyware. Note therefore that sometypes of CFi-provided sample values (e.g., keyword terms enteredexplicitly by the user as search criteria) may be automatically assignedmore of an importance for scoring likely sameness of topic than othertypes of CFi values (e.g., those that were inferred from the URL and/orcontent the user is interacting with). In one embodiment, a neuralnetwork type of weighting or statistical classifying method is used foradaptively learning through experience with the user (e.g., from gettingsurvey feedback from the user as to how well the system is providingappropriately matching invitations) what weighting factors should beapplied to different kinds of CF-provided sample points. In oneembodiment, a knowledge-base rules set may be stored for each usercontaining respective rules for handling that user's CFi-provided samplevalues, including what importance weight is to be attributed to eachtype of CFi parameter for the specific user or for general userpopulation which the specific user belongs to.

In one alternate embodiment, certain URL's are predefined in the user'sclient machine to be blind spots (to-be-ignored URL's) for whichmatching is to be temporarily turned off without disconnecting from theAARMS service. In an alternative or supplemental version certain URL'sare predefined in the user's client machine to be automatically weighteddown (damped down) focus areas so that matches are not found andinvitations are not sent unless something of unusually high interestappears on such damped down, prespecified web pages. Weighting down canbe performed in the client machine before the CFi is sent out or at thecloud end after the CFi is received, or in both places. In other words,although parts of this disclosure may seem to imply that most of thedata processing should be conducted in the cloud 150, it is within thecontemplation of the disclosure to offload some of the work on the localclient machine if that client machine has the bandwidth to handle thework. In one embodiment, the machine-implemented task of performingtrending data analysis for respective users is offloaded from the cloudto the client machines of the respective users (software and data istypically downloaded in encrypted form to protect user privacy) when itis determined that the user machine is basically idle. Users who agreeto letting their local machines be used for such distributed offloadingof the cloud's processing chores may be rewarded with reducedsubscription rates and/or special privileges. As already mentionedabove, parsing and grouping of CFi data stream items may also bepartially or fully handled locally by the user's client machine(s).

After the domain lookup process scores competing domain nodes for topicmatching and/or scores competing topic nodes under the higher scoringdomains for topic matching and so on; the higher scoring ones of thematched topic nodes (or domain nodes) are assigned with the task offinding the most co-compatible chat rooms under those nodes for thegiven user. (To be more precise, after the DLUX service identifies thebetter matching topic nodes, it sends requests to the corresponding DsMSmodules in charge of the corresponding matched nodes to find the chatrooms under those nodes that are most co-compatible for the given user.)When it searches for an appropriate chat room, a DsMS may conclude thatno currently occupied room qualifies and yet, on the other hand, thereare a number of floating users who currently are co-compatible andshould be clustered into their own room. In such a case the DsMSautomatically requests creation of such a room and sends out invitationsto that room for the co-compatible floating users.

Just because a DsMS finds a matching chat room, that does notautomatically mean however, that an invitation will be issued for thatchat room. The controlling DLUX may send instructions regarding minimumscoring requirements for issuing a corresponding invitation. The minimummatching score requirement(s) passed in from the DLUX to its supervisedDsMS resource(s) may be adjusted up or down based on:

-   -   The current number of clients already participating in the chat        rooms hosted under the specified domain or other node. If the        number of clients is low then the minimum score requirement may        be reduced in order to increase the likelihood of issuing more        invitations. Conversely, if all the rooms are crowded, the        minimum score requirement may be automatically increased in        order to thereby reduce the likelihood of issuing more        invitations unless it is a really good match for the respective        user.    -   The total number of clients that have recently submitted CFi's        directed to the specified domain or other node. If the number of        such clients is relatively low (e.g., as compared to historical        norms) then the minimum score requirement may be reduced in        order to increase the likelihood of issuing more invitations and        thus pulling in more participants into those chat rooms.        Conversely, if the total number of clients that have recently        submitted CFi's directed to the specified domain or other node        is large (e.g., as compared to historical norms) then it is        likely that many will be determined to be good matches. In such        a case, the minimum score requirement may be responsively        increased on an automatic basis in order to decrease the        likelihood of issuing more invitations and thus throttle back on        the number of new participants that will be pulled into those        chat rooms.    -   The current workload of the DsMS resources associated with the        specified domain or other node. If the load is heavy then the        score may be responsively increased on an automatic basis in        order to decrease the likelihood of issuing more invitations and        thus throttling back on the number of new participants that will        be pulled into the chat rooms whose DsMS resources are currently        overburdened.    -   The workload on the CRS resources assigned to this DsMS. If the        CRS work load is heavy, meaning that many users are not just        watching but also participating in the chat room in a more        burdensome way, the minimum score requirement may be        responsively increased on an automatic basis in order to        decrease the likelihood of issuing more invitations and thus        throttle back on the number of new participants that will be        pulled into those chat rooms whose CRS resources are        overburdened at the moment.

In one embodiment, scores for automatically deciding whether or not toissue an invitation are determined based on:

-   -   The degree of matching or correlation between the CFi, CpCCp,        and DsCCp attributes of the incoming user versus those of other        clients already in the chat room that has been created for the        domain or other node specified by the controlling DLUX;    -   The degree of matching or correlation between the CFi, CpCCp,        and DsCCp attributes of the incoming user versus those of other        clients who have been already blocked from receiving invitations        for specific chat room. In other words, if the incoming user        (the one with the now being processed CFi's) better matches with        others who are outside the chat room rather than in it, then an        automated decision can be made to create a new node with its own        chat rooms and to invite the outsiders (the outsiders who        closely correlate to one another but not to the insiders) into        the chat rooms of that newly created node.    -   The degree of matching or correlation between the CFi, CpCCp,        and DsCCp attributes of the incoming user versus those of other        clients who have been already assigned to a preexisting “catch        all” node. In other words, if the incoming user (the one with        the now being processed CFi's) better matches with others who        are inside a catch all room rather than inside the rooms of the        currently specified DsMS, then an automated decision can be made        to invite the incoming user into the catch all room rather than        inside the rooms of the currently specified DsMS. If the        participant population of the catch all room grows beyond a        predefined threshold, then the system automatically creates a        specific node in the hierarchy for that room. Whether a catch        all room evolves into being a special interest room depends on        the population of users currently using that room and the        historical growth trends of that room. In one embodiment, the        system cleaves a catch all or general purpose room into two,        retaining some participants as general purpose ones and moving        others into the special interest room based on historical trends        seen for similar rooms in other data centers. In other words, if        a new conversation is taking root across a geographical area and        spreading geographically like wildfire, the system can        automatically detect this as the new conversation takes root in        the general purpose rooms (because a special interest topic did        not previously exist for that new conversation) and the system        can begin to proactively create the corresponding special        interest nodes in data centers of other geographic areas even        before users there begin to flood the general purpose rooms in        those other data centers;    -   The degree of matching or correlation between only the CFi and        CpCCp, but not the DsCCp attributes of the incoming user versus        the same profiles of other clients who have recently submitted        non-domain specific CFi's and are not yet in any chat room        because there is no topic specific chat room that matches for        them, in which case the system automatically creates a new        general room for these personality co-compatibility new users.

In one embodiment, the invitation issuance scores are determined using amethod similar to the one the DLUX's use when rating domains or othernodes for co-compatibility with an incoming CFi. In this method,goodness values for different aspects (i.e. CFi data types and thepercentage of matches, or CpCCp/DsCCp attributes) may have differentcompatibility percentages calculated for them for determining if aninvitation should issue. Each percentage is weighted, based onimportance level, and then a total rating is derived based on theindividual percentages and their associated weights. Note: in avariation on the scoring mentioned above, the invitation scores areautomatically relayed to the client machine and displayed to the user asbasis for determining whether to join. Note: in a variation on thescoring mentioned above, the invitation scores are automatically crosslinked with other chat room invitations having same or similar scoresand these are displayed to the user as “related chat opportunities”after the user has joined one of the so-interrelated chat rooms. In thiscase:

-   -   Instead of identifying “related chat opportunities” based only        on the domain or topic node of the invitation issuing DsMS and        its position in the domain/topic hierarchy, the offered other        matches will be based on the closeness of invitation scores. In        one embodiment, a first set of chat opportunities that meet the        chat opportunity minimum matching score requirement and don't        result in exceeding the chat opportunity target count are        returned to the client machine as chat room opportunity        recommendations. The degree of recommendation may be included in        the Cciv's returned to the client.

As indicated in step 425 b of FIG. 4C, once one or more hierarchy nodematches are found for a given client's CFi values (e.g., a domain lookupscore greater than 20, for example), the DLUX starts looping through theidentified nodes based on how well they scored relative to one another.In one embodiment, for each next high scoring node, the DLUX will:

Per Node step 1: Identify the DsMS resource or resources best suited tofind matching chat rooms for this client's CFi values and based on thisclient's CpCCp and DsCCp's. The chosen DsMS resource may be in the localdata center or it may be a remote one in one of the other data centers.When choosing the DsMS, the DLUX controller may: (a) Give priority toDsMS resources assigned to local instances of the matched node (e.g.,matched domain) and thus to local chat rooms running under that node;(b) If there are no local DsMS resources available and assigned to thespecified node, the DLUX controller (or its supervising AARMS) may lookfor available remote DsMS resources assigned to the same hierarchy point(e.g., domain/topic/subtopic/etc.) but located in other data centers andthus controlled by other AARMS's; (c) If there are no local or remoteDsMS resources available and assigned to the specified node, then theDLUX controller (or its supervising AARMS) may request creation of alocal or remote DsMS resource for servicing the not-covered node andthereafter pass the room finding job to that new DsMS instance.

Per Node step 2: After identifying the one or more corresponding DsMSresources, the DLUX controller forwards the client's CFi values to theidentified DsMS resources for processing together with the client'sCpCCp and DsCCp profiles.

Per Node step 3: Upon sending the task(s) out to the identified DsMSresource(s), the DLUX controller establishes a return thread which willreceive the chat opportunity matches if any found by the DsMS resources.Upon receiving the chat opportunity matches (step 426 a), the DLUXcontroller keeps count of the total number of chat opportunities foundthus far from the DsMS resources contacted thus far and tests to see ifthe target number has been reached (and/or if target quality numbershave been reached). The DLUX controller also keeps count of the timeconsumed in looking for matches and/or the number of resources consumed.

Per Node step 4: The DLUX controller stops looking for more matched chatopportunities once the chat opportunity target count has been reached oronce a predefined resource consumption limit has been reached in termsof time and/or bandwidth times time. By starting with the highest ratednodes and stopping once the target count is met, the DLUX will usuallypresent the CFi sourcing client with the best quality chat opportunitiesthat could be found given the allotted resources. Of course, othertechniques for increasing likelihood of finding good matches may be usedand there can be a point where match scores are good enough and do nothave to be refined to being more accurate. Moreover the same concept ofgood enough applies to the room matching tasks of the DsMS's. They donot have to find the best matching (e.g., in terms of personalityco-compatibility) room for every user. There is a point where goodenough is good enough. More specifically, assume that there are 100 chatrooms under the node picked by the DLUX service. The DsMS assigned tothe task of finding the best matching room might try and survey all 100rooms. However in many cases; especially those where roomcharacteristics of the 100 rooms substantially conforms to a Poissondistribution, the DsMS surveys only the first 37% of the large number(e.g., 100) of potential rooms. The DsMS identifies the highest scoringroom among the initially surveyed 37%. Then the DsMS starts scoringthrough the remaining 63%. However, on the first instance where the DsMSencounters a room whose scores beats the highest score in the initial37%, the DsMS stops and picks that next higher scoring room as thewinner. It does not always have to (if time permits) step through all100% of the available samples. On average this method generally locatesgood enough matches. In other words, various statistical functions maybe used to increase the chances of locating good enough matches for theclient from among a set of matches without necessarily sending backinvitations for all found matches. The statistics used for sampling fromamong all found matches may be a distribution that is adaptively learnedfor different user populations based on geography, education, etc.

Per Node step 5: During its searching for hierarchy nodes havingcharacteristics matching those sought by a given one or more CFi's, itis possible that the DLUX will not find any hierarchy node correlatingwell to the CFi values or that DLUX will not find a sufficient number ofhierarchy nodes correlating well to the CFi values so as to achieve thechat opportunity target count. When this happens, the DLUX defaults to acatch-all node either under a best guess domain or to a catch-all domainnode (not explicitly shown in FIG. 4A) and test whether focus contentand current chat compatibility can be found there. Accordingly for suchcatch-all situations, the DLUX will:

-   -   Send the client CFi values to a local DsMS resource hosting a        “catch all” node (e.g., catch-all domain) and the catch-all DsMS        will make a best guess match for a co-compatible chat room based        on personality (CpCCp) and on commonality or similarity of        focused-upon content. The DsCCp's cannot be used because there        is no topic co-compatibility to match for. The catch-all DsMS        will respond with any chat opportunity matches found to have        personality based co-compatibility (CpCCp) and optionally        sameness or similarity of focused-upon content.    -   If this still fails to produce the chat opportunity target        count, the local DLUX will send the client CFi values to one or        more remote DsMS resources belonging to other AARMS instances        that are hosting a “catch all” node. The remote DsMS resources        may then respond with any chat opportunity matches found.

Referring again to FIG. 4A, accepted chat invitations are managed by CRSresources (e.g., 418) in the data center where the chat room resides. Asthe number of concurrent chat rooms and chat room participantsincreases, a Chat Room Service resource (e.g., 418) may struggle tocontinue to provide what appears to be real time communications for theparticipating chat room partners. This can be alleviated by the AARMSmonitoring Chat Room Service utilization and reassigning resources(e.g., cleaving chat rooms) and splitting up tasks to balance the load.In one embodiment, the following chat room management steps areundertaken:

Chat Room Step 1. Each AARMS monitors the activity levels of the ChatRoom Services (CRS) assigned to it. If an AARMS determines that a chatroom is becoming overloaded due to too many users and/or to manycontributions, it may take the below steps to ease the load on the CRS.

Chat Room Step 2. The AARMS will identify the CRS resources to which itsDsMS's have been sending out invitations for and those that have notbeen directed to by sent out invitations. This done by:

Chat Room Step 2a. Looking for any Chat Room Services the AARMS'ssupervised pool of CRS's (e.g., 418) which have not been assigned to acorresponding DsMS. If one is found, it will be assigned to the DsMSwhose current CRS resources are being overtaxed. The DsMS will thenbegin sending out invitations for chat rooms in the underloaded new CRSresource(s) rather than for chat rooms in the overloaded CRS resource(s)and overloading trends for the overloaded CRS resource(s) will thus bealleviated.Chat Room Step 2b. The AARMS also tries to alleviate overloaded CRSresource(s) by looking for one or more DsMS resources that are notcurrently sending out a full load of invitations and thus probably haveunderused CRS resources. If such lightly loaded DsMS resources is/arefound, the CRS resource(s) of those lightly loaded DsMS's will bereassigned to the heavily loaded DsMS which is in need of additional CRSresources and the heavily loaded DsMS will be instructed to startsending out invitations for chat rooms in the newly added CRS resource.Chat Room Step 2c. The AARMS also tries to alleviate overloaded CRSresource(s) by looking for one or more DsMS resources that currentlyhave multiple CRS resources each operating beneath its maximum workloadthresholds. If this is found, workload form the CRS with the lightestworkload will be reassigned to others of the multiple CRS resources andthe thus freed CRS resource is then reassigned to the heavily loadedDsMS.Chat Room Step 2d. The AARMS also tries to alleviate overloaded CRSresource(s) by looking for other AARMS instances that have CRS resourcesavailable for transfer to this AARMS and requesting transfer of the freeresources to itself.

Chat Room Step 3. If the AARMS that supervises the overloaded CRSresources cannot find additional CRS resources to offload the work to,the DsMS using the heavily loaded CRS will be instructed to decrease theload on its CRS resources (to throttle down) by reducing the targetnumber of offered new chat invitations (see steps 421-422 of FIG. 4C) sothat fewer users enter the chat room than there are people leaving chatroom and as a result chat room user population begins to shrink.

Referring to the UAS resource 412 of FIG. 4A, the primary focus of theUser Account Service will be to support account creation and maintenanceof user accounts. Aspects of this may include: (a) Creating a useraccount that can be used for authentication via login and passwordcredentials; (b) Allowing the user to change passwords; (c) Supporting a“forgot password” feature; (d) Entering and editing user relatedinformation, such as age, educational level, location, language, etc.;in other words, change of usern-changeable profile data; (d1) As seen inFIG. 1B, the user's CpCCp may include some of the more generaldemographics information describing the user and may include topicisolating clues such as favorite current topics, favorite currentmovies, books, etc. (154-7 a) which tend to change from time to time. Inone embodiment, the Trending services automatically detect probablechanges in the user's profile information and suggest to the user topermit automatic changes being made to the user's profiles. The CpCCpand DsCCp's will also be automatically maintained and periodicallyupdated as part of the user related information stored by the UserAccount service; (d2) Portions of the user's PEEPs (e.g., 107) may bespecific to the local client machine (e.g., 125) while other portions ofthe expression profile could be stored in the cloud 150 to therebyprovide a baseline when the user is logging in from new machines.

Further aspects of the UAS may include: (e) Automated collecting of feesfor charges like access to premium features and/or enhancement ofprofile credentials. Such automated collections may be done via creditcard or other online collection means: (a) When the account is beingcreated; (b) When a user-requested upgrade to an existing account ismade; and (c) On a recurring basis for a corresponding automaticallyrenewed account subscription. Further aspects of the UAS may include:(f) Validating a user's login credentials (e.g., including for exampleby using biometric data to validate identity biometrically) anddetermining the user's subscription level (i.e. free guest, normal, andpremium) for each login session.

Access to User Account Data Store data can be made available via thedata center backbone and through the communications firewall 419 sothat: (a) Client software can interact with the UADS (e.g., 432) inorder to support account creation, maintenance, and upgrades throughactions taken by the client software (105) running on the user'scomputer; (b) A web-based application can interact with the UADS (e.g.,432) in order to support online account creation and maintenance—Thiswould let a person create and purchase an account without havingphysical access to the user's computer, for example, a relative may buya subscription as a birthday gift for the new user; (c) Besides the UAS,other data center services (e.g., 411, 415-418) may access the UADS(e.g., 432) for the purpose of: (c1) Validating a user's logincredentials and determining the user's current subscription level; (c2)Saving changes to a user's CpCCp and/or DsCCp settings. In oneembodiment, all access to the UADS (e.g., 432) is via the correspondingUAS 412 in accordance with a service-orientated architecture (SOA). Inone embodiment, UADSs data changes are replicated to other data centerson a more or less real-time basis. This way, if as a user's activity ispassed from center to center, or a center goes off line, users will haveaccess to all the services to which they are entitled. In an alternateembodiment, the system may implement a Home center signature processwhich allows one center to query another for a user's credentials. thelatter approach might be subject to failure however if a user's homecenter is off line.

Intermixed with the various interactions between client machines andservices provided from the distributed data centers, the system mayinclude further controls for managing communications between the variousclient machines (e.g., 440) and the cloud 150. These communicationsmanaging modules may be connected to the public network 430 and mayprovide secured or unsecured instructions or recommendations asappropriate. Such instructions or recommendations may be responded to bythe client machine upon client start up if the client is not currentlyturned on and connected to the system. Some of the various types ofcommunication instructions that may be sent are:

(a) Informing a client machine of the identity of an AARMS which theclient should access in order to have that AARMS determine which DLUXwill be receiving CFi's from that client machine (either directly orthrough the AARMS). This informational communication may occur when afirst AARMS has instructed an overloaded DLUX or one trending towardsoverload to transfer some of its clients to a different AARMS forpurposes of load balancing. In this case the transferred client machinesneed to be told of the transfer.

(b) Informing a client machine that it needs to reestablish connectionwith its default AARMS in order to have a new DLUX assigned for thatclient. This may occur if the client does not have CpCCp or DsCCp filevalues that match well with a current DLUX assigned for that client andthus the corresponding DsMS resources are having a difficult timefinding co-compatible chat rooms for the client. In such a case, thecurrent DLUX or DsMS resources communicate the problem to thecommunications managing modules via the backbone and the latter thensend the “return to your default AARMS” message to the client machine.

(c) Providing rules for generating the next one or more CFi submissionsfrom the client machine to its associated AARMS or to its assigned DLUX.By defining these rules, the associated AARMS and/or assigned DLUX cancontrol the client CFi submission rates and/or submitted CFi content.This may be used to help achieve a balance between server load levelsand performance. For example:

(c.1) If the assigned DLUX has lots of bandwidth and is nonethelessfinding few well-matching nodes per unit of time for the incoming CFi's,the assigned DLUX may instruct the client to send more CFi's in atshorter intervals so as to increase the richness of matching informationand increase the chance of finding good matches.(c.2) If the assigned DLUX is running within its normal bandwidth range,it can instruct the client to not submit CFi's whose priorities fallbelow a minimum specified importance rating at least for a prespecifiedtime interval. This can work to help filter out noise from low priorityCFi's and allow the well loaded DLUX to focus its efforts on higherpriority CFi's.(c.3) If the assigned DLUX is heavily loaded, it can further throttlethe number of CFi's it is getting from its assigned clients by:

-   -   (c.3a) Communicating a maximum number of CFi's to submit per        client machine per specified unit of time;    -   (c.3b) Communicating an extended interval between CFi        submissions so as to thereby reduce number of CFi's received per        unit of time.    -   (c.3c) Communicating a set of limited types of CFi's that are to        be submitted in an upcoming time period. For example the        assigned DLUX or AARMS may instruct one or more of its clients        to submit only explicit CFi's (i.e. ones containing user entered        search request key words) and to not submit inferred CFi's (i.e.        ones based only on biometrics) during an upcoming time period.        This may help to throttle down the number of CFi's the AARMS        and/or its supervised DLUX's need to process in the specified        time period. The AARMS and/or its supervised DLUX's may use        these forms of submission throttling to help mitigate DsMS or        CRS overloads within a datacenter whose performance is being        monitored by the AARMS.    -   (c.3d) Additionally, if CFI submission throttling is needed, the        DLUX or AARMS that receives them, may choose to interspersingly        or periodically ignore one or more CFi submissions per unit of        time from one or more identified clients. For example, certain        nonpremium clients may be identified as stressing the system        more than other nonpremium clients and these identified clients        may be targeted for occasional interspersed ignoring of their        CFi's. In some instances it may be necessary to cut back of CFi        recognition even for premium clients. When this occurs, the        detected fact that a client (premium or standard service) has        not been issued any recent Cciv's may result in giving that        client elevated priority the next time its CFi's are processed.        See for example step 422 of FIG. 4C.

Example: Hypothetical walkthrough of a transaction between clientmachine 115 and cloud 150 (FIG. 1A). In this hypothetical walkthrough,it is assumed that user 111 has already logged-in into his user accountas hosted by a local data center (e.g., 410) and has been forwardingCFi's to the assigned AARMS and receiving invitations to joincorresponding chat rooms from the DsMS resources of the subject area(topic, e.g., 117 a) he was last focusing on and was last emotionallyengaged with (where emotion is inferred from his detected biometricdata). Now user 111 flips to the sports section of his online newspaper117. Client software 105 in his local machine 115 automatically detectsthe change of URL and notes that the URL is generally associated (e.g.,90% of the time) with the hierarchy domain named, “Sports” (which domainname was in this example embedded in the downloaded invitation (Cciv)).User 111 starts focusing on a particular story inside this online newspage and camera 116 detects the major focus of the user's eyeballs onthe corresponding area of the online news page. The focused on areaincludes an HTML heading containing the word “Soccer”. Client software105 can then automatically correlate the “Sports” domain name with apredefined “Soccer” topic node which it earlier took note of and isalready pre-categorized and placed in a topics hierarchy defined by aDomain Configuration Data Store (435) of the AARMS with which clientmachine 115 is communicating. Client machine 115 pings the AARMS to letit know user 111 is still reading the online newspaper and appears to beinterested in a new topic. This is automatically determined because theprevious CFi's output from machine 115 were for the topic, InternationalNews whereas now the new domain and topic are Sports/Soccer. The clientmachine alerts the cloud of the probable change of topic which wasdetected locally.

User 111 launches a web search engine in another area of his screen andtypes the search terms: “Beckham respects referee” shortly after havingfocused on the news article about soccer. In response, client machine115 generates a CFi (215 a-215 i of FIG. 2A) providing the URL plus theuser-typed keywords: “Beckham respects referee” and identifies the CFidata as a type corresponding to box 216 b. It also sets the intensityindicator 215 h to a relatively high value (e.g., +100) based on theshort time delay between when user 111 read the story and typed in theco-related search terms. For this hypothetical example it is assumedthat user 111 is not currently participating in any chat rooms, but thathe has been offered chat opportunities recently for the previous topicof interest (International News) so the minimum matching threshold forthis round is set at a medium value of, say 50.

Also in this hypothetical example, the local matching service resources(e.g., in data center 410) are operating well within their load handlingcapabilities so that there will not be a need to re-adjust the matchthreshold for purposes of load management. The CFi having theSports/Soccer hint and the related URL and the keywords is posted ontoclient buffer 215 (FIG. 2A). When a time slot for processing new CFi'sfrom machine 211 comes around, the AARMS retrieves (pulls 207 b) theposted CFi information from the client machine and forwards it to asupervised DLUX which has been pre-assigned to the Sports/Soccer node.Because the identity of the user is known, for example from field 215 aof the CFi, the DLUX (or the AARMS) can immediately fetch that user'sCpCCp file, and if the user has them, DsCCp files of the identified userthat relate to Sports and/or Soccer.

Since the root domain (Sports) and child topic node (Soccer) are alreadyfirmly established, the AARMS will not forward the pulled CFi to acatch-all DLUX that handles ambiguous catch-all CFi's. Instead the jobgoes to a DLUX that specializes in further categorizing CFi's that aredirected to the Sports/Soccer node so as to narrow the choice amonginvitations to specialized ones under the Sports/Soccer topic node. TheSports/Soccer DLUX locates in the user's fetched CpCCp file and fetchedDsCCp files an indication that 75% of the time when this user uses thekeyword, “referee”, the user is implicitly also interested in thesubtopic of “fairness” of different referees. Therefore, the combinationof the CFi and the user's preference profiles is used to automaticallyexpand on the probable topic that the user has in his head, for example,[Does famous player] “Beckham” [believe that] “referee” named X [isfair} and therefore deserves “respect”?. The DLUX scores this expandedand more focused topic as having a 60% chance of being correct based onuser 111's current mood (inferred mood, i.e., from current surroundings)and the corresponding current CpCCp and DsCCp files. Incidentally, inone embodiment, when CpCCp data conflicts with DsCCp data and topic isfirmly established, the more topic specific DsCCp data is automaticallytaken as overriding the more general (not topic specific) data. Forexample user 111 may have a CpCCp file that indicates he generally likespeaceful discussions with small groups of middle aged people. However,his Sports/Soccer DsCCp file indicates that when it comes to this topic,user 111 welcomes heated debates with large audiences of young peoplebecause user 111 believes that on-field behavior by players and refereesis important for teaching young people how to behave correctly in otheraspects of life. From this Sports/Soccer DsCCp file, the DLUX (or DsMS)pulls co-compatibility information indicating that user 111 would mostwelcome an invitation to chat room filled with young soccer fans whobelieve that players should play rough and cheat whereas user 111 wishesto heatedly argue the counterpoint. Armed with all this information, theDLUX (or DsMS) can look for a matching chat room whose detailed aspectsare substantially more refined than what could have been inferred fromjust the CFi taken alone. Accordingly, there is a good chance that user111 will be pleasantly surprised when the match-making system inviteshim into a chat room filled with young people who have been reading thesame article in the same newspaper and are of a belief that the referee(named X) deserves no respect. Now user 111 has a real time interactionof precisely the kind he has been aching for. The just-read newspaperarticle is no longer a dead inscription on a gray tombstone; it comes tolife as a hot headed mob of youngsters to whom user 111 can argue hisposition (assuming they too are in a mood for heated debate, which iswhat their CpCCp's or DsCCp's indicate).

Of course during processing of any latent CFi data stream (e.g., the oneabove where child topic node of Soccer was established), it is possiblethat the user; while in the middle of thinking about one topic (e.g.,Soccer), suddenly switches topics in his mind (e.g., because the sportssite reminded him of something else) and then the subsequent web searchmay have not have been sports related at all. The user might just aseasily gone from reading about sports to thinking about uniforms, hisdirty laundry, the price of starch, and doing a Google™ search on acompany that makes starch he is considering investing in. In that casethe assumption made by DLUX specializing in sports, that the user iscontinuing under this topic, is not helpful. In one embodiment,alternate possibilities are routinely considered in parallel. One DLUXassumes the old topic is being continued and one or more other DLUX'sare tasked with assuming that completely different domains or topics arebeing considered based on recent CFi input. If the client, or AARMS,explicitly specifies that only a single domain tree or region in topicspace should be used then lots of potentially better matches will not befound then if the DLUX's start from an assumption that a totally newdomain is possible for recent CFi input.

More generally, given the expanded information that the DLUX derives fora first user (e.g., 111) based on his CFi combined with his CpCCp and/orDsCCp, the DLUX automatically searches for potential chat partnersand/or potential chat rooms whose similarly expanded topic definitionscorrelate well with those of the first user. As each new client enters agiven chat room, the CFi values that prompted the match will get addedto the set of CFi values more generically associated with the chat room.Thus chat room profiles evolve according to the clients that enter orleave that chat room. Additionally, in one embodiment, chat roomcontents are automatically monitored to detect what words or phrases aremost often repeated. If CFi values associated with the majoritypopulation in the room are used repeatedly in the associated CFi's thenthey can be deemed to be on-topic common words or phrases and recordedas such for the associated room and/or for the associated topic node. Inother words, since they are common to the users of that chat room) theyare automatically added to the list of CFi values associated with thisspecific chat room. These actions allow the “personality” of a chat roomto build and change over time; as different people enter or leave theroom the topic under discussion evolves from one major issue to another.For example, there may be many simultaneous chats occurring under themajor domain/topic of Sports/Soccer. However, one might be about thebest equipment for amateur players to use while another may be aboutorganizing little league teams. Yet another may have been started basedon two people reading the same review of a player's (David Beckham)performance in a recent game and a third about statements David Beckhammade off the field about referee fairness. As other people joined thischat it turned into an argument about the incompetence of some refereesand whether they nonetheless deserve “respect”. This evolved chat roomwould be categorized under the major domain/topic nodes of Sports/Soccerand furthermore under a more specific node such asSports/Soccer/referee/fairness. A well operating DLUX would logicallyconnect user 111's CFi of the above example with this latter node ratherthan the other nodes.

In one embodiment, for each chat room that is being categorized by adomain specializing DLUX unit, the CpCCp and DsCCp values for each ofthe chat room participants that enters that watched chat room will be:(a) Combined following the same rules that were used when the DLUXcombined a single user's CpCCp and DsCCp values to form an expandedtopic definition; and (b) Averaged so that there are overall averagedvalues for the rules-wise combined CpCCp and DsCCp attribute values forthe given chat room. For each incoming new user and a potentiallymatching chat room, the DLUX computes a match score based on theaveraged chat room characteristics versus the new user's preferences andexpanded topic definition. In one embodiment, a score of 0 indicates abad match and a score of 100 indicates a great match. In the givenhypothetical example the chat room discussing whether referees actedfairly receives a good match score because there were strong keywordmatches to the terms: “Beckham”, “respect “referee” as well as to theexpansion derived keyword, “fairness”. The Chat room discussing the bestequipment to use did not score as well because there were lacks ofmatching on the primary keywords.

More generally, a chat room match score is calculated by the responsibleDLUX for each of the possible chat rooms under consideration byassigning match value to various aspects of the chat room topic based onthe clients' topic preference profile. Thereafter, the assigned DsMSnarrows the list of potential chat rooms to which the first user (e.g.,111) might be invited based on personality considerations. Aspects thatmay be considered include: (a) The number of people already in the chatroom; (b) The conversation tone (i.e. peaceful versus heated debate)where the latter may be determined based on participant supplied votes(supplied via their Cvi's 118 b where the votes are either explicitlystated or inferred from the biometric feedback data). The conversationtone may also be determined based on detection of keywords or phraseswithin the chat conversations that indicate tone. Each topic andpersonality co-compatibility aspect will be given a value based oncomparing the client's preference to the chat room's state. The valuesfrom each of the evaluated aspects are then combined to produce a chatroom match score. A score of say, 50 may represent a neutral outcomewhile a score of 0 may indicate a bad match and a score of 100 mayindicate a great match for the user who is potentially to be invitedinto the given room.

In one embodiment, chat room match scores are calculated as follows: (a)A neutral starting score of say, 50 is (assumed; (b) The DsMS willcompare each of the DLUX supplied client's CpCCp or DsCCp preference's(i.e. level of topic proficiency or expertise) to a correspondingaverage of the chat room's current participants. Favorable comparisons(i.e. the average age of the participants in the chat room matches, oris close to, the age preference stated by the DLUX supplied data) willincrease the sequentially adjusted score. Unfavorable comparisons willdecrease the score; (c) The calculated match score may also be adjustedup or down based on individuals in the chat room, for example, if theclient has indicated that they never want to chat with a specificindividual who happens to be inside the chat room then the chat roommatch score is forced to 0. As another example, if the client hasindicated a preference for chatting with a specific second individualwho happens to already be inside the chat room, then the chat room matchscore will be increased. In one embodiment, the final score will bebetween 0 and 100. In this example the chat room discussing refereesscored well because: (a) The DLUX specified client did not indicate apreferred domain expertise level so that aspect of the chat room profilewas ignored; (b) The chat room had attracted many other participants ofyoung age in accordance with the first user's desires as expressed inhis DsCCp, so there was a positive affect on the computed match score;(c) one specific person whom the first user likes to chat with, wasalready inside this room resulting in the neutral score being furtheradjusted in a positive direction.

In some cases, numerous chat rooms may score for a positive match. Inthat case, the DsMS will evaluate the well matched chat rooms in theorder of their scores. The chat rooms with the highest scores will beevaluated first. In this example: (a) The chat room discussing refereefairness is evaluated first, because it scored the highest. It meets theminimum threshold for the match score and so it is added to the list ofpotential chat opportunities to be handed back to the DLUX or sent backas an invitation directly from the DsMS; (b) If the chat opportunitytarget count has not yet been met, a next chat room on the list isevaluated; (c) In a case where the chat opportunity target count is notyet reached by evaluating preexisting rooms, the DsMS will look foropportunities to create matching new chat rooms by inviting in otherusers with similar preferences into the newly created rooms. This may bedone by:

New Room Step 1: Find the list of potential chat partner clients thathave recently submitted CFi's directed to the same hierarchy regions(e.g., same current domain) where the submitted CFi's are in common withsome of the CFi values submitted by the DLUX expanded topicidentification of the first user (e.g., 111);

New Room Step 2: For each client in the potential chat partner list,retrieve their profile settings: (a) CpCCp values will always beretrieved; (b) If the DLUX indicated a specific domain, and not the“catch all” domain, then DsCCp values will also be retrieved if anyexist for that node;

New Room Step 3: For each client in the potential chat partner list,rules-based combination of CpCCp and DsCCp values will be used as theclient's preferences relating to this set of CFi values; for example,when topic specific DsCCp values are found they will override genericCpCCp values.

In this following hypothetical example two potential chat partnerclients have been identified. Both were selected because they hadsubmitted the CFi value “referee” in reference to the domain/topic ofSports/Soccer.

New Room Step 4: The DsMS calculates a cross matching score for eachpotential chat partner client in the list against the first user. Forexample, a potential chat partner client CFi score will be calculated bycomparing the DLUX expanded client's CFi values to the CFi valuesassociated with the potential chat partner client from the list. In oneembodiment, this will be done by using the same algorithm used tocalculate domain matching scores when comparing the client's CFi's tothe domain node's average CFi's. A score of 0 indicates a bad match anda score of 100 indicates an excellent match.

In this hypothetical example, one of the potential chat partner clients(Bob) CFi's consisted of only “soccer” and “referee”. This resulted in afairly high score. On the other hand, the other potential chat partnerclient (Bill) CFi's consisted of “soccer, Referee” and ten other termsthat did not well match the DLUX expanded topic values for the firstuser (111, e.g. Sam). Although the number of positive hits between thetwo potential chat partner clients was the same, the ten terms that didnot match caused the score for this second potential chat partner to belower.

In one embodiment, a potential chat partner client profile score iscalculated as follows: (a) A starting score of 50 (neutral) is assumed;(b) The DsMS compares each of the chat room preferences (i.e. number ofparticipants, conversation tone, etc.) declared in the CpCCp or DsCCpvalues for both the first user and the potential chat partner client;(c) The DsMS compares each first user's CpCCp or DsCCp preference fileattributes for a chat partner (i.e. age range, level of domainexpertise, etc.) to the corresponding demographic settings (i.e. Actualage, declared or verified level of domain expertise, etc.) from thepotential chat partner and vise versa; (c) Favorable comparisons (e.g.,declared level of expertise matches requested level of expertise) willincrease the score. Unfavorable comparisons will decrease the score; (d)The calculated scores may be adjusted up or down based on dislike orlike for specific individuals involved, for example, if the one user hasindicated he never wants to chat with the other person then the scorewill be set to 0; (e) On the other hand, if either client has indicateda preference for chatting with the other person then the new chat roommatch score will be increased. The final score will be between 0 and100.

In this hypothetical example the potential chat partner, Bob was on thelist of individuals the first user (Sam) indicated he never wanted tochat with so their resulting cross compatibility score was 0 for thetwo. The other potential chat partner client Bill had no CpCCp or DsCCpvalues in common with the profile values supplied for the first user(Sam) so the score was left at a neutral value of 50. The CFI andprofile scores will be combined to create a matching score for eachpotential chat partner client. In our example potential chat partnerclients Bob and Bill each scored poorly in one section so neither of thematching scores was very high. The potential chat partner clients willbe evaluated in the order of their scores. The potential chat partnerclients with the highest scores will be evaluated first. In this exampleneither of the potential chat partner clients met the minimum matchingscore so neither was added to the list of potential chat opportunitiesto be handed back to the DLUX for forming a new room. Therefore the chatopportunity target count is never reached before the time out clock runsempty.

Users of the match-making system do not have to be passive receivers whomerely wait around for new invitations. They can actively change the waythe system is organized (e.g., how the domains hierarchy tree of FIG. 4Bis organized and/or how topic nodes are mapped onto a given topic spacesuch as the one shown in FIG. 6) by casting votes and makingsuggestions, including suggestions to merge out-of-system rooms oron-topic resources into the system. (By out-of-system rooms or on-topicresources, what is meant here is that these rooms or on-topic resourcesare not yet linked to by corresponding on-topic nodes of the system'shierarchy tree. Out-of-system rooms may also be ones for which thesystem has no rights of control, such as controlling who enters theroom, etc.) In one embodiment, a client can try to explicitly subscribeto a given chat room even if not automatically invited to it by sendinga message to the Chat Room Service (CRS 418) in control of the room orto the AARMS that supervises that CRS. The uninvited joining into a roomrequest should contain a chat room identifier which is typically postedin the room. Once the CRS accepts the subscribing user, the user will beable to (through his or her client machine): (a) Send messages into thatchat room; (b) Receive all messages posted into the chat room by otherparticipating members; (c) Get alerted as other members enter or leavethe chat room; and (d) depending on whether only premium users or otherspecially classified room users or anyone can, get to vote on changingthe name, description and other system-stored characterizations of thegiven room.

In one embodiment, any member of a first in-system chat room can requestthat a new second chat room be created or that a current room be cleavedor that a third room be merged in with the first room by sending acorresponding request for new room creation, cleaving or merger to theroom supervising CRS. (By in-system room, what is meant here is thatthis room is logically linked to by at least one corresponding on-topicnode of the system's hierarchy tree and also that the system has controlrights over the room. It is possible to have out-of-system rooms forwhich the MM-IGS does not have control rights.) Part of this request mayinclude recommending a name and description for the new or altered chatroom(s). The user requesting reformation of the first room or creationof the new second chat room can also specify if the modified room is tobe a public room or a private room. The supervising AARMS may be askedto get involved in grant of request process because load balancingissues may arise. Upon grant, the DsMS that is the CRS resource's parentwill be notified that the new chat room has been created or one or moreprevious rooms have been modified (e.g., merged). If the new/modifiedroom is a public room, the DsMS may start using that room when lookingfor chat room opportunity matches. If the new/modified chat room isinstead designated as a private room, it can only be entered viainvitations authorized by the user who initiated formation of theprivate room or via invitations authorized by another user who isdelegated the task of controlling entry into the private room. Anexample of an invitation authorization might be for example, invite onlyoutside users who have a PhD degree in advanced biophysics and who alsoattended an Ivy League school. The DsMS would inherit this authorizationcriteria into its match-making criteria when performing its match-makingtasks.

In one embodiment, users of a given chat room may invite specificoutsiders to join that chat room. Such invitations to join the chat roomwill be initiated by a request sent from the inside client to the ChatRoom Service hosting the chat room. The CRS or its supervising DsMS willthen pass the invitation directly to the specific outsider as a Ccivrecord or packet without its DLUX having received a corresponding CFifrom that specific outsider. In an alternate embodiment, the CRSreceiving the request will determine which AARMS is being used by theoutsider client who is being invited to join the given chat room. TheCRS will then pass the invitation on through the default AARMS used bythe client who is being invited in. If that invited outsider is off lineat the moment, the next time that client contacts his default AARMS, theAARMS will respond with the stored and awaiting invitation in the formof a Cciv.

When a newly created or user-modified chat room is a public room it: (a)May temporarily appear in the domain hierarchy tree under a node that isa child of the node pointing to original room from which the requestinguser initiated the new room creation or old room(s) modification (e.g.,bifurcation or merger); (b) May be used by the DsMS when looking forchat opportunities for users who have not been specifically invited intothe new/modified public room; (c) May get included as a “related” chatroom recommendation provided at other nodes or in other rooms.

Users within all or a system specified subset of chat rooms may performcollaborative actions. An example of this may be to set or change systemstored data representing chat room settings. Some chat room settings canbe defined or modified based on recommendations of the chat room users.Here are some examples: (a) A new chat room created from a user'srequest can have set properties such as being private or public, havinga specific room name and description set by the creating user and/or canhave a specific node position in the domains hierarchy tree andinterrelated nodes or rooms pointing to it or it pointing to them; (b)Preexisting public chat rooms that were not locked down (i.e., notdesignated as unalterable because they were created to support dynamiccreation of new domains and topic node or because they are part of apredefined domains hierarchy tree backbone) may be specially allocatedfor allowing users to meet there and collaborate on chat room names ordescriptions or descriptions for other rooms. In other words, thestructure of a large set of branches within the domains hierarchy treemay be debated about and agreed to in these collaboration rooms. Theprocess might occur as follows:

-   -   A user submits a suggestion to the CRS.    -   This suggestion is automatically broadcast to the other users in        the chat room who have agreed to weigh in on restructuring        suggestions.    -   One or more of the other users may make alternate or        supplemental suggestions.    -   These additional suggestions are also automatically broadcast to        the other users in the chat room.    -   Each of the plural suggestions is voted on to reach a group        consensus. The votes may be submitted in the form of Cvi's cast        by users participating within the collaboration room.    -   As the votes are collected and a collaborative decision is        reached, the AARMS, DLUX and DsMS responsible for the chat room        will be automatically notified of any changes that might affect        future match-making tasks.

Cvi Processing: Like the CFi's, Current Vote Indicators (Cvi's) arerecords or packets or other data conveying objects that are formulatedand generated in one or more of the local client machines at thelocation where the user is interacting with one or more open chat rooms(e.g., 316 a, 316 b of FIG. 3A) and where the user is implicitly orexplicitly expressing vote-like opinions regarding content presented inthe open chat rooms (and/or in other online exchange forums). In oneembodiment, implicit voting is automatically inferred from collectedbiometric data of the user where that collected biometric data is deemedto strongly correlate with the content presented in the open chat roomsor the like. In one embodiment, each Cvi indicates at least one of: (a)what portion of the inn-chat-room content is being voted on, (b) aemotion or reaction type (e.g., inferred from biometric feedback)associated with current or previous inn-chat-room content, and (c) avote on, or rating of current or previous inn-chat-room content.Additionally, in one embodiment, each Cvi may further indicate (d) adegree or intensity of an emotion or reaction type concurrently reportedin the Cvi. In some cases, the vote on, or rating of the identifiedinn-chat-room content may be in the form of a simple “yes” or “no”; orsimple “positive (+)” or “negative (−)”; while in other cases the ratingmay be a value within a predefined range (i.e. on a scale of 1 to 10).For example, a 0-100 scale might be used to rate another user's level ofknowledge about and/or proficiency in a topic being discussed in thechat room. As mentioned, Emotion types may be accompanied with a ratingscale value of their own.

Implicitly or explicitly produced votes (as conveyed by the Cvi's) canbe used to smooth interaction and/or collaborating with other users invarious chat rooms. As mentioned above, if a majority or super majorityof participants in a given chat room implicitly or explicitly expresspersistent negative votes on the inn-chat behavior of one user (e.g.,because that user is behaving like a troll), the chat room supervisingservice (CRS) may responsively bifurcate the room and thus separate theunwanted user from the others Also as mentioned above, voting may beused to migrate a room to being situated under a new or different nodein the hierarchy tree and/or towards renaming the room or its node. Hereis an example of steps that would be followed in one embodiment:

-   -   A room user proposes a name, or a name change, for the current        chat room.    -   This proposal is automatically presented to all or a preselected        subset of the other chat room participants.    -   Each authorized participant is enabled to cast an explicit or        implicit vote (via a Cvi) regarding the proposal.    -   The votes are automatically counted over a predetermined time        limit and the proposal is approved or denied according to room        specific voting rules. Rules relating to approving the proposal        may require one of the following:    -   A simple majority of the votes submitted or of all the        participants in the chat room where that number may have to        exceed a predefined quorum.    -   A specified percentage (i.e. 60%) of all submitted votes or of        all the participants in the chat room.    -   The voting will end and the results will be displayed after:    -   Enough of the chat room participants have submitted votes to        determine the outcome, or    -   A predefined voting time limit has elapsed.

Implicitly or explicitly produced votes (as conveyed by the Cvi's) canalso be used to adaptively adjust a given user's CpCCp and/or DsCCpvalues and/or knowledge-base rules. Examples of this include:

-   -   Reducing a first user's verified proficiency level within a        given topic, if the user receives negative feedback from other        chat room users having verified higher proficiency levels in        that same topic (in other words, subordinates are graded by        validated ones of their superiors in the same topic).    -   Setting or altering a first user's preference or dislike for        certain other people or chat rooms if the first user shows a        history of consistently voting contrastingly for or against such        other people or chat rooms.        Using the above techniques, a user can participate in a domain        specific chat room without having a personalized DsCCp (e.g., he        or she as a new corner has only a template DsCCp). As the user        interacts with chat rooms in the domain, the user's reputation        values and/or credential values in the corresponding DsCCp can        be developed automatically based on implicitly or explicit votes        cast by others in the room.

Implicitly or explicitly produced votes (as conveyed by the Cvi's) canbe used to adjust profiles in real time. They also may be stored forlater evaluation by trending analysis services. For example it may benoted that a user who is usually fairly balanced in their voting hasvoted extremely negatively over an usually large percentage of the timeduring one evening. From that it may be automatically inferred that thisperson is simply in a bad mood or ill on that one unusual occasiontherefore those negative votes will not be counted or they will beweighed less than what how they are normally weighed (based on theuser's reputation, credentials, proficiency level, etc.).
